face rat 

A person who spends all day assing around on Facebook looking for status updates in which they can post perverted or otherwise obscene comments on. Face rats also enjoy being tagging or being tagged by other face rats in pictures of things like: men with titties, women with fupas or penis or vagina shaped objects.

All of my friends are total face rats. We check our new notifications like a pervert checking his mail box for porno mags hoping someone has commented on the totally disgusting yet hilarious picture of the hairy guy with titties we posted.

Bead rat 

Attendees of a Mardi Gras parade that collect the dirty beads dropped by other parade go-ers. They are often voracious, nasty, sneaky, and annoying in getting these leftover beads.

Hey! Look at that nasty bead rat hoarding all the beads from the piss-lined street!

Asian rat candy 

A very suspicious and interesting looking conglomeration of matter that often turns out to be better than expected. Often referred to in the context of food but can also be used to explain things or events.

I went to his house for dinner. I had no idea what was on my plate; just a huge mess of asian rat candy stew or something.

In reference to a business presentation:
"Dude! I just killed that! I wasn't expecting it to be such a a buffet of asian rat candy success."

Resin Rat 

A person that is obsessed with collecting the tarry residue from pipes used to smoke marijuana. This residue gives a mild buzz when smoked and is used as a last resort by some smokers. A resin rat will go to great lengths to get this tarry substance and will even smoke it when bud is present.

Man 1: Wow, Jim is really going to town on that bowl.
Man 2: Yeah, he's a regular old resin rat.
