Its when someone holds his dick and starts moving it up and down so it makes a sound like fap fap.
Yesterday I saw my brother fapping in his room.

Fap is when you are all alone the parents just left the house and you get the feeling in your stomach. You know what's coming, the urge takes over your mind and that's all you want. Time for fap. To grab ones dick in his/its hand and violently try to rip it off.
Keith: Hey Kevin when was the last time you fapped
Kevin: Yesterday Keith
Keith: How was it Kevin?
Kevin: ohhhhhhhhhhhh MAN i busted all kinds, all kinds.
