Urban Rodent 

(Euphemism for "Hood Rat")

A language love child of internet slang and possibly l33t 5p34k. It's an almost unreadable mix and match of lowercase letters, numbers, and opinionated acronyms, which are often beyond morally and grammatically incorrect. It's commonly used to make ignorant points during internet arguments via Facebook and/or Twitter.

(IM in "Urban Rodent" VS. English)

Syrian Rodent Bath 

A sexual act involving a hamster, where two people fuck aggressively in a toilet stall of a fast food restaurant, and just as the man is about to ejaculate, he pulls his penis out of the woman. He then takes a hamster, grabs its paws and starts to stroke his penis using the hamster until he busts and drops the hamster into the puddle of semen on the floor. Occasionally, the hamster will bite the man's penis in self-defense, resulting in blood and an even bigger bath for the hamster.

I went to McDonalds the other day with my girlfriend, and in the toilet, we performed the Syrian Rodent Bath

lip rodent 

A bushy mustache, particularly one confined to the upper lip. Often grown for Movember by fools who don't know their head from their ass when it comes to proper facial hair grooming.

Yeah, I fucking dumped that lip rodent sporting tool; he spent so much time looking in the mirror he forgot to brush his teeth.
