Someone who is washed up, has gone soft, and no longer commands respect in the hood. From Ice Cube's song "Check Yo Self."
"You're gone, used to be the Don Juan, now your name is just Twan."
-Ice Cube, "Check Yo Self"

Carlos: "Whats up dogg, long time since you been back in the hood."
Tony: "For real. What's going on with J.D. these days? That dude used to run shit around here."
Carlos: "Fool has gone soft. Now he ain't nothin' but a twan. He settled down with some bitch and she's got him whipped. I saw him last week walking her weak-ass chihuahua around the block, cleaning up its shit and shit. Then I saw him with that ho the other day going into the movies to watch 'Confessions of a Shopaholic.'"
Tony: "Man that is some mark-ass shit! We gotta straighten that twan-ass bitch out. Let's ride on that fool."
Carlos: "Word."
