Crepe shark 

Someone completely addicted to crepes and can't stop

Bob Belcher: Gene, look at me. You and I both know your mom's not coming back after just one crepe. She's not gonna stop, Gene. She's never gonna stop. It's who she is.

Gene Belcher: If she stops, she'll die. Like a crepe shark.

Creep Shark 

A creep shark is a person who sneaks behind an individual, or group of individuals, while they are having their picture taken, and has only their eyes and nose exposed over some region of their body visible to the photographer.The ideal creep shark is wearing sunglasses and a hat and is unnoticed by the group getting their picture taken while he/she peers over them. While in progress, the creep shark is said to be "creep sharking".

Oh my God, Stacy! There is some creep shark in the back of this picture we took last night!"
