To Pull only the tip of your penis out showing it to someone else as part of the penis showing game. This results in two kicks in the ass and being made fun of for being a fag to the person getting the gratutiy.
(around a corner) Hey Davy! You want a tip?
Yea sure.
(While kicking him in the ass) What a fucking meat gazer.

A gesture of satisfaction, sometimes confused with a tip. However, the tip is just the start, it is only a tease, after that, you give the full gratuity.
"I wanted to show her how much I appreciated her, so I gave her the full gratuity, not just the tip."
