Do you know where Jared is? Next time you see him, tell that ratfink bastard I'm going to tear out his scrotum for knocking up my sister.

Timmy's the kind of lazy ratfink that leaves half a sheet of toilet paper on the roll just so he doesn't have to replace it with a new one.

ratfink 

a cross between a rat, a fink, and a mouse. This is an odd animal only found in seclusive arounds in western egypt. It evolved quite a bit ago when a natural formation of toxic chemicals spilled on to a fink colony in the ground. The smell atracked rats all over the world to partake in the delicious meal. The finks, only half dead at this time, were consumed by the rats and were absorbed into the rats' DNA due to the nuclear contents of the fink. This disaster was the end to Finks, but the birth of ratfinks. However, this disaster made the rats shun the ratfinks because they were different.

A: Look, a ratfink!
B: What's a ratfink?

Ratfink 

A douchebag that sleeps with his ex girlfriends cousin and doesn't think anything of it. Ratfinks usually have no job, no car, and sleep on peoples couches for 4 months at a time. They also tend to have wide nostrals, a pointy nose, and a lack of chin. Beware; ratfinks love to cheat. Stay away from any ratfinks you know...they may be contagious.
