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.

Can be used in two cases. One for the girls and one for the guys. When this is said to a girl, it means dont play with other blokes dicks. When said to a guy it means dont touch up my girl (rhubarb being a nice sweet dish when added with sugar, girls being nice and sweet)
Boys: Hey man, thats my girlfriend you're trying to impress. Stop it, never rub another mans rhubarb.
Girls: Hey there bitch what you doing? That guys coming on to you. Remember I'm your boyfriend, never rub another mans rhubarb or else. (fight)
