In the game Skyrim, when you Fus Ro Dah you blow a shout/air at people, creatures, or object to push them away.

When used as a sexual term, it's when you yell "Fus Ro Dah!" and cover a woman's pussy with your mouth and blow a lung full of air up her
My wife was pretty pissed when I Fus Ro Dah'd her last night
