knowwhatimsayin? 

Said as if one word, it means "Do you understand what I mean?" but during the peak of its use it ended up midway through many sentences and regressed into having no meaning whatsoever (i.e. similar to the Canadian "eh?").

Original meaning: "We're just chillin' down at Lawrence and Ellesmere, knowwhatimsayin?"
Peak use: "There's this cat, knowwhatimsayin, he brings three gats to the block party, knowwhatimsayin, and he's got beef with one crew, knowwhatimsayin, etc."
