Tightly wound toilet paper that is used to absorb blood from having gotten your "cheeks busted" (prison raped). Often used daily 2 to 3 days after an incident.
"Chadbusted my cheeks on the yard, gotta use a manpon for the next few days."
if a mans been walking all day and his taint starts getting chafed, he makes a quick stop at the restroom, grabs some toilet paper, wets it down, and applies it to his taint. like a tampon but for a dude.
-basically to combat swamp butt.
dude I can hardly walk anymore. my ass is on fire. i need to hit a restroom and make a quick manpon.
