I dont really know where that one comes from but its a very well used word here.Thrash said:The term that really got me when I moved to Australia was 'bash'. If someone is assaulted, seriously assaulted or almost murdered, on the news and in the newspapers they have been 'bashed'. Whenever I hear it I can't help but think of Dennis the Menace or somthing like that.
Its all so another word for masterbating in some places. "im gonna go have a bash"
