Sheet shark 

Waking up with a morning throbber while your partner is asleep still, you try to sneak your hard one into her ass while the sheets are still in front of you.

You want sex but you know she will not want you to wake her so you go for the fast kill and try to slide it in, but you get caught by the sheets(Sheet shark)!

Sheep and Sharks 

That Guy believes that everyone is either one of these two creatures. Sharks are winners and they don't look back 'cause they don't have necks. Necks are for sheep.

“Let's cut to the chase. There are two kinds of people: sheep and sharks. Anyone who's a sheep is fired. Who's a sheep?”

sheepshark 

A rabid underwater creature that looks like a shark covered in thick white wool except for his face, his fin, and his tail. He likes the shallow water and is often known to feed on human flesh.

Jesus Christ, it's a sheepshark! Run away!
