Giving head, or more specifically, a description of a young lady who hasn't given up her virginity yet, but does indulge in after meal tubular snacks ending with cream.
Overheard at a wild party: "I know she's inexperienced in many ways, sexually, but she does eat crayons. I can see from the crust on her upper lip."
