That one guy who sits around playing World of Warcraft and Minecraft all the time, to the point where it's taken over his life. You think he's you're best friend until about 6 months later you begin to realize how big of an asshole he really is. Brians will make insulting jokes, they'll put you down, try to get with your best friend after dating you, and they'll call you names for no reason because they are mentally still an immature 8 year old girl. Not all Brian's are terrible, but it tends to be the Mexican Brian's you meet that will stab you in the back.

Get the Brianmug. A small penis-wielding china man. He is commonly found in the parks looking at little girls. Beware of Brian, because although his penis may be small, he tries to put it in every hole he finds. This includes coin slots, doorknob holes, and electrical sockets. Usually you'd want to avoid anyone named "Brian".
Guy 1: Hey I heard Brian is coming to the party.
Guy 2: Gross bro, I heard he tries to molest children. I'm not coming.
