1)When one's codename/nickname is discovered. Meaning, if anyone that the name is supposed to be a code to has figured out who that person actually is, their actual identity has been revealed.
2)When you are found out/caught by (ex: the cops/school/ parents/ect.)to be known by whatever nickname you go by. When those who aren't supposed to know, know your nickname. Hence, you must lay low from doing crimes or tagging it up or you may get arrested since they know who you are and so on.
A nickname can be "berned out" in many ways for example the following
-ratted out/snitched
-caught tagging in any way
-recorded evidence of multiple people refering to you as that name
-a lot of hit ups or just wrighting of the name on any body part or many belongings owned by the person refered to by that name

Logic: Ay foo, you know Downer?
Clever: Yea, I know that foo.
Logic: Yea, well his name got "berned out" foo. The cops caught'em taggin it up down Main Street and they arrested his ass. So they won't catch him in the future by the same name, he's changing it to Little Loc.

"All my son does all day is sit in the basement phone-banking for Bernie Sanders all day while listening to the Red Army Choir. He's such a bern out, I really wish he'd grow up."
