look up any word, like slope:
 
1.
Bum wank.

Arse wank.
"Go have a batty fap you battyfapper."

"Quit your battyfapping!" - Stop being an arse wanker.

The term Battyfapper may be used to describe the profession of male and female strippers, who parade their batty for the fapping pleasure of their audience.
