battyslag 

Someone that is both a batty and a slag, derives from the two words gay and whore. Often Battyslag's are found annoying people that are having a good day, questioing their career choices and generally being a pain in the arse. To get rid of a battyslag, simply give them a slap as they are extremely sensitive to being touched.

"Do you know this boy called Liam Connelly??" , "Yes I know him, he is a battyslag"
