Urban Dictionary

A website with a minimal amount of useful information, but where a lot of kids with too much time post completely made-up bullshit terms that they hope will catch on, and about topics of which they know sweet-fuck-all - such as SEX. Examples include cock-taco, donkey-punch, chili-dog, space-docking, and any other ridiculous scenario that could only transpire in the fantasies of a desperate virgin.

#1: Dude! Last night I shit on this girl's tits then I rubbed my dick in it then I made her suck my cock! It was awesome!!

#2: Dude, totally, me too I love that shit it's so funny! We should call it something and put it on Urban Dictionary! But for now I'm gonna go play WOW and jack off in my parents' basement!

Urban Trade

Urban Trade is a relatively new retail clothing store, and I've only seen one of them in all my mall experience. They mainly sell Billabong, Quiksilver and the british brand Bench. Trying to find anything else there is near impossible. Not only is there a limited selection, but it is way expensive as well, and most things there can be bought at other places (even West 49) for a much better price. However, the store is very nicely layed out and very clean and tidy inside.

"I would have bought those Billabong jeans from Urban Trade, but West 49 had the same ones for $10 less"
