on 10 perc 

on 10 Percocets, a short version of "how he stand on 10 perc???"
often used in the context of video games, to describe something that shouldn't be standing/be there but is.

it comes from a joke in the thumbnail of the video "19 Year Old Father OWNED in CSGO" by FranzJ, and has been used by many video creators and streamers playing fps games.

Percocet is an opioid, which has an effect similar to morphine, so you shouldn't be standing after taking 10 pills.
