this is where you spread your ass cheeks and engulf the face of a sleeping "friend." this action generally occurs when someone is passed out, or asleep and woken up suddenly. waking up suddenly, and engulfing your own face in someone's ass is what gives the "ham samich" the name designation of "flying"
I was asleep and heard a buzzer. I woke up suddeny and planted my face into an open and waiting ass to recieve my very own flying ham samich. thank you.
