Courtesy Splash 

When you are watching a movie with a bro and a sad part comes up. Your bro begins to cry so you throw your drink in their face so no one can see that he is crying.

Dude, thanks for that courtesy splash when Obi-Wan died. I would have been hella embarrassed.

Courtesy Stall 

The act in which a man using a public restroom will seperate himself by at least one stall as a courtesy to another man that is already established at a separate stall. This can be done either at a urinal or a traditional stall.

I walked into the bathroom and noticed that of the three urinals available, a man was occupying the one on the far left. I gave him a courtesy stall and went to the urinal on the far right as not to appear gay.

Courtesy Spit 

Before having intercourse, if your partner's vagina is a little to tight, you can take a light amount of saliva and lube the tip of your penis with it. This will allow easier and smoother insertion of the penis.

Your pussy is too tight, let me throw some courtesy spit on my dick.

courtesy sheet 

A sheet that is put down when fucking on a bed that is not your own. The sheet serves as a barrier between sex juices and your friends bed.

Hey Lee, you can only fuck on my bed if you put down a courtesy sheet first.
