momster

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.

step momster

A nasty stepmom who always has a resting bitch. Face is unpleasant and treats, her husband and her husband’s family like garbage but her own family can do no wrong.

My step momster got her own kids something lovely for the party but only got my kid a crappy cheap trinket.

Momster is when a scary and angry man does a satanic ritual and becomes what we call a momster. Momsters can be very dangerous but you will know when you meet one because they are sus as fuck.

Momster truck

Oversized school run SUV capable of going off-road but will never scale more than kerb. Perfect for driving over kids on bikes and other lesser vehicles.

Sorry I'm late. The road was jammed up with stupid momster trucks doing the school run.
