Name used to describe someone who enjoys bathing in their own filth. These people have the ultimate "I don't care" attitude. They have very greasy hair and oily face. The word "hygiene" appears unfamiliar to them. They often have very few teeth by the age of 30 or sometimes no teeth at all. Not to mention, their body odor is powerful enough to make you go blind.

Synonym for Rapasse.
I'm going to Walmart today and will probably encounter a Rat de swamp.

The city bus was filled with Rats de swamps last night.

I haven't showered all weekend and I feel and look like a Rat de swamp.
