Moster

(Noun) A student who uses the Mos debit card to save money for college. Generally the coolest friend in the group and somehow always matches their card with their OOTD. Savvy and thrifty, but definitely not cheap.

Student 1: Whoa, Paige just told me she landed $12k in scholarships for this year!
Student 2: Not surprised, I'm pretty sure she's a Moster.

Moster

Moster means when something is cute and adorable but deep down is bad and evil.

Bro, that puppy looks sweet, but it’s a total Moster.

Moster

Basically ghosting but worse, mostly found on tinder. Tries to get close to you and lies about being interested just for intimate relations then proceeds to block and unadd you from everything.
