Hippononymous 

A quiet, shy, and content hippopotamus that frequently sends brilliant pieces of writing to literary magazines under the humble and secretive name of anonymous.

-Dude these articles are so insightful and enlightening!
-I know man... I wish I could tell the world about this author but I don't even know who wrote it!
-Yeah man, must be a Hippononymous. Much respect to that mind.

It is someone who is really cool once you get to know them. Just one of those people that never stand out and for some reason you meet them one day and you become good friends.

Ross was hipanonymous to kate because he looked gay and she later found out he wasn't and became attracted to him because of his coolness
