When a young man coppulating with a young lady on a beach decides to pull out and dip his love wand into the sand only to return his member into her fruitful passage leaving the poor unfortunate female squawking like a seagull.
The squawking seagull does not need an example.
When having sex on the beach or any other sandy surface near a large body of water the male removes his penis from the female vagina, dips it in the sand, then reinserts his penis into the vagina thus causing the female to squawk and scream.
My girlfriend wont go to the beach with me anymore since I gave her the squawking seagull last time we went together.
when laying on a beach you throw sand into a girls vagina
Guy1:"oh dude did you see Tim just give that girl a squawking seagull"
Guy2:"Oh damn i missed it"
