A small (usually 5–10 homies) tight-knit group with members ranging from young to old. There’s a street posse in every hood — from old heads to youngins — usually linked by a shared purpose. Could be music, repping a neighborhood acronym, chasing a hustle, or just putting on for the name. Not always about crime, but always about loyalty and presence.
“Yeah, that street posse really be on the rap tip — they not street dudes like that fr, more studio gangsters than street gangsters.”—Everyone from uptown

The most hype NFT community on Twitter, we spend our day scouring the web for PSSSSD references and stalk Lab Techs during our free time, we also take a break on Sunday.
Yo man, the posse just spent an hour in a Twitter space where the host fell asleep and no one was talking: dopest community.

The Poss head is a manikin head (often used for wigs) that is possessed by an evil entity. The Poss head's purpose is to posses people and be the new host of their body. This entity is a nothing but a myth as it hasn’t been proved to actually exist. The word “Poss” is short for possession and “head” because it’s a manikin head.

A large group of grad students at Penn State who drink away their worries every week (and usually multiple times per week) at a hole-in-the-wall bar. Generally only consists of science-minded grad students. (N.B. The "groovy" times do not always have to involve alcohol, and can, in fact, involve many different substances.)
Last night I went out with the Groovy Time Posse, and bitched about undergrads while taking tequila shots.
