The name of a person. Cosmos can sometimes be very annoying, and quite the sumpstpug. But they will still always be that one friend that will always be the life of the party. And you can always count on them to have great fashion.

A Cosmo is fierce, brutal and savage. She is a dark haired angel, expelled by God for veing too powerful and resorted to devilish ways to fulfill her intelligence and ADHD. A Cosmo has many faces, and is the direct competitor to God, hence his fear for her. Cosmos are sweet, innocent and seductive, until you break their heart with injustice, and they will reign fury down on anyone. Cosmos are romantically suited to Ians, but make no mistake a Cosmo cannot be manipulated with words, only pure actions can seduce a Cosmo. Cosmo are intelligent, perceptive and intuitive and they make great team leaders.

They are a kind, funny, sarcastic person that will always be there for you. They're always ready for a hug. Them or their parents might like astrology, they might just like the name, who knows? But you should always love a Cosmo. <3
