Never rub another man's rhubarb!

Yes, its from the first Batman movie in 1989. It means stay the fuck away from my girl. It is part of the code. No friend of mine is allowed to talk to or hang out alone with my girlfriend unless they want the wrath unleashed upon them.

"What the fuck man? You took her out to dinner last night? Never rub another man's rhubarb."
