A crude sexual act where a woman tries to take a shit while the man shoves the turd back up into her ass with his dick.
This crazy bitch tried to give me a hot lunch, but I got the jump on her, and gave that turd the old dirty plunger right up the corn sleeve.
When you take a dirty, truck stop plunger and you stick it over your genitals and you rip them off. Then you take them and stuff them up your ass. Then lick the plunger clean.
"I'm so high and nothing can hurt me. Time for a dirty plunger !"
