Stabby is a person that has stabbed someone, but has not been convicted yet.
Chantal said Stabby only stabbed his ex-girlfriend and cousin because he was scared they would take all the drugs from The Traphouse, and Chantal wouldn’t want to pay Stabby’s rent anymore because there was no drug supply left, and Chantal wasn’t gonna be able to Beeze like the Beezer she is.
