Fapburp 

When you take a massive wank ... towards the finish line when your just about to drop the load you do a massive burp at the same time. Basically the female version of the multiple orgasm, with a risk.

Fabio - “mateeee , I just did the biggest fap Burp , it really hurt , and I was a little scared , but it was unbelievable.

Crispin - “wow you really must have hit the beers and pop hard last night. Fapburping is the best thing ever !!” Fapburping completes me.

Fapburn 

The term used when an excessive masturbator whom knows no bounds creates so much friction between his hand and his member that his palm burns.

John: Oww, my hand still hurts from yesterday..
Bill: What happened?
John: I got fapburn..
Bill: You should probably masturbate slower, or even better, less.
