Thanks to the wonder that is the Google Web, I have been exposed to a vast amount of regional and international slang words. I'm particularly tickled by some of the expressions our American cousins come out with.
My current faves are -
Douche / Douche Bag / Douche Nozzle - for those unfamiliar with a douche, it's an applicator women use to clean their lady gardens (or rinse out their stinky muffs as Mother would say)
Made of Win - if something is good, then it is made of Win, if it is really good, then it is made of Win and covered in Awesome sauce.
F**ktard / Motard - a variation on the retard insult.
Kool Aid Drinkers - People who are easily led and a bit stupid. I think this refers to one of those religious cults in America that drank poisoned Kool Aid soft drinks so they could all die together.
Gunt - the distended belly of an overweight lady that sticks out under tight jeans and covers her nether regions.
And just to bring it back to the UK -
Twunt - two naughty words mashed together
Anyone else have any particular faves?
