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.
