Girl 1: How are things with Will?
Girl 2: Ah, I'm so disappointed. He seemed perfect, but every date with him feels like forever because he's so dull.
Girl 1: Haha, he sounds like a total doorknob. You'd better ditch him.

Guy 1: Dude, look at that girl over there. Pretty hot, right?
Guy 2: Oh, Stacy? We used to date, but then I realized she was a total doorknob. Nothing to her. She can barely hold a two minute conversation.

A farting game. When someone farts who is playing the game, he/she must say "safety" before another participant says "doorknobs." If "doorknobs" is spoke before "safety," the farter can be punched in the shoulder unless said farter touches a doorknob. When played by veterans, the pre-fart safety, "pre-safety," can be employed for no more than two minutes to allow for those times of uncertain gastric distress.
Me: <fart>
Other: "Doorknobs!"
Me: Moves toward closest doorknob too slowly.
Other: <smacks me in the shoulder hard>
Both: Laugh.
