1) the post-coital vaginal smell that remains, albeit subtely, on a man's body, even after showering, for several days. This smell, undetected by the human nose, serves as an aphrodesiac and thus attracts more women to whoever "has the stank on" them.

2) a hot streak with the ladies resulting from "the stank" being on one's body

1) You'd better go out tonight, you've got the stank on you!

2) He's been on-fire lately. Looks like he's still got the stank on him!
