Cosimo 

An amazing person, he always knows how to answer questions and is loyal to all his friends. He is the best at sports in all his classes and takes everything competively and likes to tease others when they lose. In the end you can just say he is a G.O.A.T aka Greatest Of All Time

"Yesterday I was destroyed by Cosimo, He is just too good."

cosimo 

A cosimo is a person who has fingers longer then 10 cm long, and is therefore amazing at bridge. If you see a cosimo walking down the street, you should run away, buy a house in Ipswich, change your name to Nathaniel and stay in that house for the rest of your life because cosimo is probably coming after you. In 2011 a Cosimo was at the top of the CIAs kill list for the touching of several million goats, and he will not hesitate to touch you either. And always remember: he's behind you!

Mark: I saw a Cosimo today.

Ben: you do not know me
(Ben proceeds to cut all connection between himself and Mark in case Cosimo comes after him)
