My initials are BJB.
I was in jazz band in high school. We were doing a joint thing with the choir, so everyone was running around moving stuff to make space. My parents had bought me a nice music bag with my initials on a plate on the front of it. Someone held up my music bag asking who owned it. I figured they just wanted to let the owner know where it was being moved to, so I spoke up... "Hah, your initials are BJ!"
Hence, my name became blowjob. The completionists called me Blowjob Betty (I'm male) to get that last initial in, too. At the time, I was quite quiet and took myself maybe a little too seriously. This ended that.
One day, I was at my buddy's place, and he called me "Beege," saying he didn't want to say "Bee and Jay," as it was too long. At that point, I said fuck it. My name is Beege. Let's go.
Over time, my friends added an article because why the fuck not.
Over 20 years later, and it's still my name. It actually taught me to not take myself so seriously. Although, one interviewer at a job had a really hard time keeping it together when HR told her my nickname without catching the meaning. She and I are good friends now.
In any case, I always get a slight chuckle inside when people hesitate slightly after introducing myself. I'm great at keeping a deadpan face about it now, too
