What is Paddy's Motorbike?
1.
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.
this hole's ready for filling, we'd better go and borrow Paddy's motorbike.
