When you're with someone in a public situation that you shouldn't be with and you touch elbows to signify you want them.
<<at a restaurant>>

Woman 1: places arm on table but within reach of guy.

Guy 1: places his arm on table and discreetly touches elbow continuously with woman since they can't do anything else. Ie...kiss or have sex.

Guy 1: "Hey, how was lasts night date?"

Guy 2: "Dude, sucked! Waitress was a mutual friend and all I could so was elbow date!"
