A cool guy. Normally sweet and sensitive, especially to women, a Gaelan can become friends wit girls easily and mistaken as a flirt. A Gaelan may often be mistaken for another meaning of Gaelan, but is still cute non the less. A white Gaelan, ruffly around 5'8 is known to be amazing in bed.
Girl 1 'Hey who's that cute guy over there?'

GHirl 2 'OMG he's such a Gaelan, I love him already!"

Get the Gaelan mug.
Common terminology for an older male at central North American comic/anime/science conventions. A Gaelan usually "creeps" on young girls dressed in cosplay by following them around the convention centre or watching them from afar. A Gaelan is usually crossdressing and uses it to strike up a conversation. Tends to be very into roleplay; uses it in sexual ways.
Example 1:

S: "Hey Alannah who's your friend there...?"

A: "Oh just this guy I met, he's cosplaying Nana!"

(Pulls Alannah away so he can't hear)

S: "Dude he's a total Gaelan! Ditch him!"

Example 2

G: "You... have epic cleavage."

S: "I'm only 16, gtfo!"
