James Island swamp rat

An individual who lives their entire life on an island 2 miles south of the battery in Charleston. The typical hobbies of a James Island swamp rat include drinking every waking moment and being obnoxiously loud and destructive in common social settings.

We had a great time out in Charleston last night until the JI swamp rats showed up and got us kicked out of the bar. Typical James Island swamp rat behavior.

Rat de swamp 

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.

Breeding like swamp rats 

They breed us in to a ghetto Human population that can no longer support an independent middle class home. They filled the homes with their swamp rat spawn. Now their kids and us live in stacked apartments eating and shitting on top of one another. No land to grow food, paying off the sins of swamp rats with taxes and rent, making life hard for everyone.

Clint Eastwood - how many swamp rats can you fit in one home? They are breeding like swamp rats.
