Colm is the Irish equivilant.
Colin does mean Victor or Victorious as mentioned.
Id also have to agree that Colin is a man who falls deeply in love with a woman.
He's really cool too and usually a sharp character, doesnt particularly like Colm though.
Colin gets irritated when people get his name wrong, e.g. Connor, Colm, Colon, Cailin, Conan.
Colin's girlfriend: Ya.....
some random chic: your so lucky... i wish i could sleep with him...
'Is he good in bed?' 'Oh, he's a Colin'
A musician in heart, with the ability to pull his own passions and power together and give that gift to the world.
(Girl2) I know I want him to ask me out.
