If you've ever suffered the crushing heartbreak of being cast asunder by an online pal, you're probably pretty familiar with the term "unfriend".

Well, it look as though even the internet-phobic are set to become accustomed to the phrase, as "unfriend" enters next year's edition of the New Oxford American dictionary.

The term, which originated on social-networking sites such as Facebook beat "sexting", "intexticated", "netbook", "funemployed", "hashtag", "paywall" and "greenstate" for the title of Word of the Year.

According to a senior lexicographer, the term has (we kid you not) "lex appeal"...

Oh dear. In a frighteningly embarrassing bout of "spontaneity" employees over at the newly opened Mission Viejo Microsoft store burst into an impromptu line dancing session. Fair play to them for keeping it up for a nerve-wracking 4 minutes, despite the store's customers clearly either uninterested or too embarrassed to look.

I hope these poor cogs in the Microsoft machine got a nice bonus for this little stunt. Their tired feet and tainted souls sure have earned it.

You know you've really won over the hearts and minds of a nation when you get to star in your own web game. Either that or someone hates you that much to spend sleepless nights developing one that rips what's left of your flailing credibility to shreds.

Enter "Grimes Against Humanity", starring X-Factor hate magnets John and Edward.

Players must bounce "Jedward" to the top of the voting tables in a bid to win over the cruel destroyer of pop-worlds, Overlord Cowell (inexplicably portrayed by the Mousebreaker-developed game as German).

You know what's wrong with all these new smartphones? They just look too sleek. What I really want is a gaudy, bling-tastic phone, unofficially themed around my favourite dead popstar. If you too are looking for something a little more, ahem, off the wall, then this Michael Jackson phone may be for you.

With faux diamonds and moon walking silhouettes of Jackson etched on the back, the gold coloured handset is a sight to behold. Made by a Chinese imitation "shanzai" company, the phone comes packaged with a suspect-looking live DVD.

The "limited edition" phone is extremely garish, but in terms of knocked off gear, you can't beat it.

Zombies, zombies, zombies; just when will we stop getting a kick out of maiming these lumbering, brain-eating foes? Not any time soon if game developers Valve have their way. Left 4 Dead 2 is set to hit shops on the 20th November, so get ready for another frantic blast of four-player, undead whacking first-person madness on its way.

The highly anticipated sequel takes place in the Deep South, where four brand new survivors are battling against the zombie horde. Valve promise three horrific new Special infected foes, the brand new addition of melee weapons, and a refined version of the AI Director that made the original so replayable.

Check below as Tech Digest's very own Gerald Lynch gets prepped for the zombie horde with an SAS survival training session.

As if the Segway wasn't daft enough, look out for the Yike Bike, weaving its way into oncoming traffic next year.

Designed for urban travel, it's able to reach a top speed of 20km/h, weighs 9.8 kilograms, and can fold up for easy transportation when not in use. It all looks a little bit dangerous, coming across a bit like a tech-savvy clown's unicycle.

That said, it's not half as mad as the roller-blade suit below. I know which one I'd prefer...

Iwantoneofthose.com is always a great place to pick up a last minute gadget gift for a loved one. But what do you get the person who has everything? How about a paintball battle in a WWII tank? It's just one of the ludicrously fun sounding days out now available from www.iwantoneofthoseexperiences.com.

Here are the top five experience days heading our Christmas lists:

Tank Paintballing - £94

Regular paintballing is all well and good, but you look like a bit of an idiot running around some cold wet forest off the M1 with what amounts to an over-powered spud gun in your holster. Enter "Tank Paintball", where you and two mates take control of a hulking 17 tonne FV432 armoured personal carrier capable of firing 40mm paint rounds. Imagine the bruises in the morning...

Jousting - £199

Is there a fair-maiden whose looks warm thy loins? Well then, young squire, why not win her hand by competing for her affections at a day of jousting? Participants of all riding abilities are welcome, and we've been assured that the losing knight will not be beheaded.

Spy Games - £219

You may have the missile-launching car, the jetpack and the laser-wristwatch. But do you have the skills to go with all those spy gadgets? A day at spy school will teach you all you need to know to carry out covert-ops deep in enemy territory.

Ghost Hunting Break - £199

Fearless adventurer? Why not pop Ray Parker Jr. on your iPod and head out on a spooky paranormal investigation in a haunted house? Derek Acorah, eat your heart out (and then come back and haunt me to prove you weren't making it all up).

Ice Climbing - £59

Remember February's ridiculous snowfall? Get prepared this year by taking part in a day of ice-climbing that would make Bear Grylls shiver.
