Basically, an April Fool's prank. Get an Oreo, take out the white stuff and put white tooth paste (hence the "mint"). Give it to someone and watch their reaction. They should later (in about 30+ minutes) be running to the bathroom with diarrhea.
Guy 1: Hey, want some mint oreos?
Guy 2: Sure.
Guy 1: *hands oreo*
Guy 2: ...These taste funny...
*About 30 minutes later*
Guy 2: Oh shit.
Guy 1: What?
Guy 2: I have diarrhea. I just shit myself.
Guy 1: APRIL FOOL'S BITCH.
Guy 2: Sure.
Guy 1: *hands oreo*
Guy 2: ...These taste funny...
*About 30 minutes later*
Guy 2: Oh shit.
Guy 1: What?
Guy 2: I have diarrhea. I just shit myself.
Guy 1: APRIL FOOL'S BITCH.
