a very common insult used alot on the internet between "friends" basically the same as ya mam
and ya mum
but because people cant be bothered to press the space bar now and then yamam seems so much easier. Can be used in all kind of situations and either ends up killing (ending) the conversation or u end up gettin bitch slapped. is also an opputunity to expand your small vocabulary by adding other offensive terms to piss off ur mates. is normally the only answer u can get from a question no one wants to answer
yamam has got to be one of the best words in the world, now go forth and engage in the phenomenon of YAMAM!!!
