An arse wank is when you stick your fingers in your arse and have a wank. You can either stick your fingers in your arse and wank your cock, or stick your fingers in your arse and move them in and out and wank your arse.
Oh gosh I had such an arse wank last night, my arsehole exploded and it looks like the mariana's trench!

To do like a dog does when it has worms or an itchy arse. To literally place ones 'knock hole' on a surface and orientate 180 degrees in one direction and then the other.
