When you are in the shower and you stretch your foreskin to collect the water as if you were a bucket. then dunking your head into the foreskin and using your teeth to pick out the smegma.
Last week, I heard that Charlie Lyon was cheese-bobbing in the shower.
Commonly misrepresented as "Spongebob Squarepants", Cheesebob is a cartoon character who lives under the sea, and has an impressive array of friends.
Nobody really knows why Cheesebob was changed to Spongebob when he clearly is not a sponge, but a block of cheese.
Charlie: Dude, I can't go to the library with you, Cheesebob Squarepants double-bill is on at 5pm!
