John : **Lifts finger up**
Victim : ? U tellin me to wait? *Smells fart* Oh my god what’s that smell??

This means they are a sad gay loner, with a hairy shit covered cum stained taint you don’t want to associate yourself with. The person that does this pose gets 0 bitches and will probably die a virgin. Being drunk is not a valid excuse.
Girl 1: look at this photo isn’t he cute

Girl 2: ye but look he’s only holding his pinky, middle and index finger up

Both: *proceed to projectile vomit followed by deleting the photo and ghosting him for the rest of eternity*
