Cosmo can me used to describe the galaxy.
It also can be a really cool name for an animal, such as a dog.
"Woah... the cosmo is really pretty..."
"My dog's name is Cosmo! I believe it suits him..."

The greatest boy in the world, cares more for his hair than anything else. Loves everyone and anything, always be there for me.

Doesn't matter what sex you are, he is always easy to talk, Hates keeping things from people, if they need he will tell him.
He can't lie to someone, it's impossible for him to do that. He loves dogs, and humans.
He's the person to turn to if you are ever in doubt. Even if you are going out with him, you can talk to him about anything about the relationship.

He is also known as the fairy god parent from the 'fairy god parents'
