Spike Rat 

A small rodent that lies underneath the folds of flubber of an obese man. The rodent survives in hot moist areas of the body living off of sweat and missed food particals. If is very docile and can be easily trained. Can grow up to the size of a toy poodle.

Did you see the Spike Rat that was living between Billy's flubber? I think the Spike Rat was eating cookie crumbs.

The Tubba Rat

When you are engaging in unprotected gay anal sex and a small piece of undigested material such as corn or a peanut gets lodged in your pee hole.

Tubba was on all fours getting his daily ass pounding when his boyfriend suddenly yelped like a cocker spaniel when a piece of corn became lodged in his urethra. Tubba tried to suck the corn niblet out, but it was a full-on case of the Tubba Rat.

Dirty Sewer Rat 

When you are inside a disgusting public washroom stall taking a dump and you get a chick to suck your dick during the process. When you are done pooping, she licks out your ass then you spin her around and stick your dick in her ass while shoving her head in the toilet that you have not flushed(this is crucial). After she has eaten approximately 50% of your shit start effing her in her pussy and slap her back with your right hand hopefully forcing her to puke up your shit. After this is accomplished take her out for an italian dinner and a movie.

Dan: Hey Dave I saw you and Kim out having dinner last night at Little Sicily, what was the occasion?
Dave: Oh nothing, we just did the dirty sewer rat earlier that evening.
Dan: No way! Did she eat enough of your shit?
Dave: No, but I let her get away with it.
Dan: That was nice of you dude.
