Fap
fap - a code word used to masturbate usually used by males.

me and my friends have started using this word recently since we heard of its meaning.

we use it as part of a scale of how far someone has 'gone' with a girl.

gandered - kissing
fap - petting
pwned - intercourse
Alfie: pwned her yet then?
Adam: nah just fapped, and gandered.
Alfie:k
