The Partygoers! 

An entity of The Backrooms, most commonly found on Levels: FUN, 119, and 188.
Partygoers are highly aggressive, and highly intelligent.
They create Balloons and can mimic the sound of laughter, these are used to lure you to them.
Partygoers are tall slender bright yellow (sometimes other colored) entities that appear to have a smile carved into their "face", inside their "sleeves" is what looks to be similar to a lamprey eels mouth, Partygoers will latch onto it's prey and convert them into one of them, Partygoers can create, alter, and delete wiki pages of information about them.
Partygoers are silent, but lack in speed, so you could easily outrun them.

Christmas Partyhoer

A person--usually a married co-worker--that uses the company Christmas party as an opportunity to get extremely drunk and dance inappropriately on other co-workers' spouses, usually leading to embarrassment the next day.

Todd: Dude, Steve is all over the boss' wife

Phil: He's such a Christmas Partyhoer. That's going to be awkward tomorrow.
