(Action Verb) When a guy is balls deep inside a woman's vagina, one of the participant rips a fart while the other feels their rumble. This is known as a Volf. With synchronization and planning, it's possible to have a Double Volf. This is when both participants fart simultaneously and both feel the rumbles, sometimes off the richter scale.
Guy: I'm about to cum, oh my god....ahhhhh
Girl: Yea baby
Guy: Hooooold OnNNNN!
Guy: Done! Babe don't move......(FAAAAAAAAART)
Girl: Wow, you just Volfed me!! You just broke my Volf cherry.
