What is a "party board"?

I grew up in a state where I got to snowboard a bunch and for the past 10 years I've been in a state that doesn't get much snow. I've been out of the game for a bit.

Started looking into more ground tricks, buttering. Really impressed with a lot of the buttering teachers on IG.

Then I came across this term: Party board.

Is this just a board that's really good for buttering and jibbing? Going down the mountain friends kind of slowly, hitting 180's on small lips on the run?

Carving and giant air aren't really my thing

I searched Google for a definition and couldn't really find one.
