A momster is something your mother can turn into when she flips her shit and freaks out at you. This normally happens when: 1) you cut your own hair 2) you pierce yourself 3) when you break something 4) when you accidently say something in front of her that is more of a "friend remark" or 5) when you accidently drop your guinea pig that she really loves to feed.
