When you've got a threesome going with two girls, one is laying on top of the other, and you alternately penetrate each one, i.e. insert penis into the top girl, then withdraw and insert it into the bottom girl, then the top one again, then the bottom, ad infinitum until orgasm. This is flying the cock. Originally coined by Jeffy of RSD.
I flew the cock with Sydney and her mom last night dude, it was awesome--Jeffy would be proud!

I'm flying the cock bitches!
