A Key Rat is one who lived in Key Biscayne between the 50s and 70s and actually operated as an organized crime gang. Up untill the 90s The Key was in the dark ages. In 90s there was a resurgence, a renaissance, a true enlightenment of ruthlessness and debauchery. These young men became known as Mid Side Kings. They lived in only a 3blk radius from "The School" aka K.B. Elementary. After about 2002 or so there have been only wannabes and groupies riding the fame of these brave men.

A Key Rat is one who has a record, dead, in jail, been to rehab(and it's not for chronic sweethearts), f*cking your gf, beats up bouncers, gets up on US1 and everywhere else, robs houses, rims, jewelry, your bitches, and anything he can get his hands on. He would also move large amount of weight, threw "V's"(violations), get rushed, rumbled without even thinking twice, feared, respected, envied, jocked, and being a degenerate and charming at the same time. Just had to clarify a lil before you dare calling yourself a Key Rat. Had Real Beef with real gangs and crews, and affiliated with Real G's b/c u gotta be one to be down.

mad love to the other True Key Rats:KMOB,KB,HIV, and rest of u. u know who u are.
Living in The Key does not make you a Key Rat, nor does having BMW, Audi, Mercedes, or any other luxury car.
Being a Key Rat is a lifestyle, not a catch phrase.
I saw a Key Rat crack that guy in the head with a bottle.
I started beef with one Key Rat, and suddenly like 20 started hitting me.

n. similar to a Cocoplum Gangster. This is a rich, spoiled, wannabe-thug who lives in Key Biscayne or "The Key" as they call it. Typically can be seen driving the Mercedes-Benz or BMW his mommy and daddy bought him. He might be affiliated with a "gang" and may even threaten to slap you with his wallet.
The Key Rats got in a fight with the Cocoplum Gangsters on the other side of town over who had the more expensive car.

A trashy chick that is on the D.L. 24/7. Hence, the term "low key". Many are opptimistic about her secret life and often engage in taking guesses about her dick taking abilities.
Alex: I bet she rides dick like Seabuistcuit

Cole: No way my brown friend! She's the pastor's daughter

Alex: Dude, gaurentee she's a low key hood rat.
