look up any word, like blumpkin:
 
1.
A style of sexual foreplay that involves the use of an old school plunger. Either partner sticks the plunger to their belly button and proceeds to have usual intercourse until they make a sound that is similar to that of Gary the snail.
Dude me and my gf were watching sponge bob and I got the weirdest boner. So I went in Gary Plumb ed my lady.
