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.

Momster truck

Oversized and unnecessary school run SUVs that are capable of going off-road but will never scale more than kerbs. Perfect for driving over unseen kids on bikes and lesser vehicles.

Sorry I'm late. Traffic was snarled up with the school run momster truck parade.
