A sexual act in which the man inserts his erect cock into a woman while they are both stood facing each other. The man then proceeds to spin the woman around in a full 360 degrees motion, giving the appearance of a plane propeller spinning around its prop shaft.
Dude, that girl was begging me for a Vietnamese Propeller last night but my cock just wasn’t strong enough!
