2. A challenge issued wherein the subject must complete a task they threw out sarcastically. If they do not finish the task, they risk being punched.
3. Something your asshole friend says when they know you're joking, want to see you fail miserably and want to hit you for it.

A: Yeah, right, I'll totally ask that chick out.

B: No butter, dude. You have to do it.
