When someone comes out with a witty comment or funny line which they have taken from a film or television show. The
embarassment comes when they are
caught out, and someone reveals to the rest of the group that what was just said was not their own wittiness or quick thinking.
Getting "quote red-handed" is especially
embarrasing if the show or film being quoted is an embarassing one.

Short Person: Haha. You just got quote red-handed.
John: Haha. *And* you watch Tracy Beaker!
Jack: Dude. So do you.
