the guy who heckles your open-mic set

He is the guy in the back who laughs at your worst jokes and heckles your best ones, purely to get a rise out of you - then somehow he's the one still there when the lights come up, offering to walk you home. Troublemaker exterior, patient sweetheart underneath.

A regular at your open-mic nights who makes a sport of heckling you. He also somehow always ends up walking you out after.
