The act of flipping ones boner up into the waist band of ones pants to avoid an awkward public erection. (gym short not recommended)
Guy-So I was with my girlfriend and a group of her friends the other day and I got a boner. We were in the mall so I had to pull a boner-flip...
Friend-you weren't wearing gym shorts, were you?

Taking Ecstasy then/and either viagra, levitra, or any other medication for a limp dick in order to more quickly achieve a boner while rolling.
Dude, did you see Murph last night? He was boner flipping and got a boner while getting a light show at the rave.
I boner flip every time I roll now.
