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)
