Motorbiking 

While doing doggy-style, you insert you thumb into the girls arse several times, with your hand in the same position as if you were throttling a motorbike

JD took that girl home, bent her over, and ended up motorbiking her!!

paddy's motorbike 

a trench rammer or "Wacker" - basically a petrol engine driving a flat stomper, used for compacting earth back into a trench or flattening local repairs in tarmac.

So called because of its prolific use by apparently irish road labourers.
