dookie shark

When you take a shit and it's so enormous that it sticks out of the water in the toilet bowl, like the dorsal fin of a shark. Commonly found in low-capacity flush toilets.

It's always a shock to look down in the toilet and see a dookie shark staring up at you.

Retarded Shark

A dance move in which you put your right wrist over your left wrist. Your left hand is facing towards you, but your right hand is facing away from you. and you sing. It is sung in the tune of the baby shark song. When singing you bend your wrists.

A great way to break Awkward Silences.

Everyone: **Awkward silence**
You: Retarded Shark do do do do do *repeats*

attention shark

A person who craves so much attention, if they don't get enough they'll die, much like how if a shark stops swimming, they'll die.
