A wannabe gangster that dwells in the streets of New Jersey where the thugs are tough and the education even tougher. Is prone to making up insults over the internet to try and make his low-self esteem not appear as bad as it is, though most people know his dad beats his self esteem out of him every night.

He is also capable of intensely destroying the English language with every sentence to point where they call him the Hitler of literacy. Personally, some believe this man to want the English language to disappear all together.

When approaching a wild Cosmo just be prepared to be yelled at and attempt to be instigated into a fight, though you are the pussy if you don't go to fight him and not vice versa.

Be extremely cautious.

Very dangerous.

Hurts feelings.
Yo, this fugazi nerd tried to pull a Cosmo on me.

But I put him in his place like the rest of the world puts Cosmo in his place. Especially his dad.
