To inconvenience someone (can be either used as a noun or a verb)
v. - Aww, man. How are you gonna slater me like that? I front $500 for courtside seats and you tell me last minute you have a date??

n. - By standing me up, that was a real slater.

(I think Mario Lopez's character, 'JC Slater', from "Saved By the Bell" has something to do with this definition. I didn't make it up, my friends from the east coast used it)

Slut + Hater = Slater. Usually a girl who hates other girls who don't have to fuck to get a guy to like them, and because of her low self esteem will hate on the girl who gets guys without trying. She is a dirty girl who f's everything.

Used to express farewell. The term was originated by the townspeople of Slater, MO because they thought it would be cool to say “Slater” instead of “Later” due to the fact that they rhyme. It is also be a combination of “See Ya” and “Later.”
Well Gene this party was a rager, but we now have to go, slater.
