While having sex on the beach quickly stick your penis in the sand then re-insert it into your partner and watch them flap around like a seagull.

the seagull is a maneuver for the "penis showing game" from the movie "Waiting" an uncircumcised guy takes both index fingers and middle fingers and stretches his foreskin open making it look like a seagull and taking his pinkies at the same time and holding his nuts up to make the wings
he flashed the seagull at the new guy within the first hour
