While eating a girl out and simultaneously jacking off, you chomp down on her vag, come on her face and yell "I am the DUNGEON MASTER" then run out the room.
"Yo bro, did you finally fuck that girl or just Dungeon Master all over her face?"
"Dude, I fucked my ex last night."
"Yeah, the weird thing was it was after I Dungeon Mastered her."
"I know brah... I was there"
