When you, or someone else is at a party and they just
don'
t fit in. Eg, sober at a phrat party. Common name for this person is "Gary". Often think they're the main attraction but everyone just wants them to leave. Gives of a rapey/
creepy vibe.
"Man, i showed up to this party after work on
Friday, everyone but me was wasted. I was a real beef cheeks on the
chin but I
stuck around anyway. Drove home sober at midnight"
