When you fart, and the fart comes back up to your labia. Feeling like a wave of vibrations.
Friend: Did you just fart?
Girl: Yes, girl and it travelled to my labia feeling like a vibration. That's what a vart feels like
Friend: That's cool!!! What's a vart?
Girl: When you fart out your ass and it travels to your labia, feeling like vibrations.
When you vomit and fart at the same time.
Kelly was so fucked up last night that she ended up pushing too hard and varted in the car.
