Gratuity 

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."

The Gratuity 

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.
OHHH THE GRATUITY!!!
(While kicking him in the ass) What a fucking meat gazer.

The act of having extremely loud sex so often to the point where your roommate/neighbors ask you to keep it down/lock it up on a regular basis.

Guy-"So did you get any sleep last night?"

Other guy-" No, my roommate was having Gratuitous Sexy Time with his girlfriend. It was so loud that the police came and told them to keep it down."

Guy-"Damn, that sucks."
