look up any word, like dirty sanchez:
 
1.
Skash is a term used generally by girls to boys. It is the male equivalent to sket. It is aimed at boys who get around a lot, spread sexually transmitted diseases, those who are generally overly suggestive and dirty minded. A skash has several uncommitted sexual relationships and he often mixes up girls names as he has lots on the go at once.

It originates in Milton Keynes, UK. At a school, called Stantonbury Campus, a class of year nine students made up this word as they felt there was not enough words for these types of men.
