Cosmos describes one of the hottest guys on earth. Their sweet and funny, with a slightly cool (but not "I'm all that)" vibe to them. They laugh easily and are playful! He's one of the best friends you can get! No matter what, you know you can count on him.
1. I went through such a hard time this year. It really showed me who my real friends are. My best friend was such a Cosmos.

2. Cosmos is the best.
