Get the No umug. 
It's basically a word used in the modern internet word. It means that if someone says that someone is "Haha you're gay" but in this occassion, they say "No u" back, which turns their words against them.

Steve: “If you haven’t left yet, I’d leave early to be on time! The line of cars is backed all the way up to the stop sign if you’re coming from the west.
Bob: “I’m not worried about it, I’ll just pull a Jewish U turn.”
