Colby's usually use Gus as a nickname.
These boys are one of a kind.
they can be your best friend,
or best boy friend. :)
even if you aren't his girl friend, he will treat you like your the world to him. He is always looking out for his friends.

You always know when a Colby likes you.
They are usually very attractive, with amazing blue eyes.
They can make anyone laugh, and are class clowns
If you want a best friend or an amazing boy friend,
get yourself a colby(:

An old English name with even older Nordic roots. It's derived from the Old Norse word "Kolbyr", which means "cold settlement". Also a kind of cheese, but don't bother joking about it with someone named Colby. I guarantee you they've already heard it.

You might not want to name your kid this if you live in the southern U.S. People there have a habit of saying "Koby" instead, and it might drive them nuts.
A lot of these definitions for "Colby" are obviously written by some guy who's really insecure about the size of his member.
