Famfap 

The more technical and scientoligific term for committing an incestuous act.

when your girlfriend/boyfriend blow you and right before you cum they put a coffee cup to the tip of you dick and you cum in the coffee.

my girl said she wanted more protein in the morning so she asked if I could help her make a fapfappuccino with her eggs and bacon.
