a keiser is someone who is a massiv Bøv and a biggit. He often says dumb thing like "what up guys are we going to the pub today" and make dumb jokes nobody laughs at.
a person of Malaysian decent and a casual gym-goer, he is generally an incredible chad and is labelled "Mr, steal yo girl", be careful if you find one of these in the wild, but always confront with kindness.
