An acronym of Kiss My Teeth. Basically, when you dissaprove of someone, or you want to show your dislike of them, you sort of put your tongue over your front teeth and make a little kissing noise (whilst giving them a dirty look). So writing KMT is telling the person that you don't like them.
KMT means Kiss my teeth which has its origins in Africa and the Caribbean. It usually means ‘whatever’. To some elders it’s extremley offensive and should not be done especially in countries such as Jamaica.
