A Brian is a flaming faggot that refuses to come out of closet. Typically makes non-quality gay jokes about straight men. Also known to play butt tag with other Brian’s. In 2015 research confirmed 98.7 percent of all Brian’s were closet homos.

Get the Brianmug. Of Celtic origin. Often Irish with blonde hair and blue eyes. Charming, but deceitful. Creates wonderful allusions without being fully dedicated to the subject. Overall a good time, but leaves you dissapointed in the end.
