Fart Block 

When at a social gathering and there is a guy hitting on a girl. Walk over next to them, fart, then walk away. The girl will think that the guy hitting on her farted, get grossed out and ditch him. Essentially cock-blocking via farting.

Friend 1 - "Haha dude that girl just completely rejected that guy trying to hit on her."
Friend 2 - "That's because I fart blocked him."
