Kicking a female in the vagina hard enough to send her to her knees.
In an attempt to get out of the brawl, Sheila clam dropped the butch broad blocking the door.
Clam Drop is when anything falls out of a womans vagina. Like an airplane bomber drops a load of bombs.
My girlfriend said that she ate the M&M's but then I saw her do a clam drop all the way to the bathroom.
