One bat 

when someone is to give a 'one bat' they hit someone with the back of their hand really hard.

A ruthless smack on the face.

in eastenders when Ronnie gives Janine the 'one bat' and falls to the ground in one hit.

One Night in Batista 

An underground pornography which featured current WWE superstar Batista and one unknown male accomplice. Towards the end, Batista powerbombed his lover through the bed, injuring him severely. Consequently, it has been removed from the internet for fear of lawsuit.

One Night in Batista was the most erotic porno I've ever seen.

Batch one off 

To masturbate and “batch one off” a selfless act for a friend who does not have gel for their hair prior to going out.

Oh my God we’re almost at the club and my hair is a disaster, can you please batch one off for me?
