BDB
A bdb refers to a person who obsesses over having a giant cock. He goes around considering himself the big dick bandit.

However, the truth behind the BDB is that he is a bandit who steals big dicks.

A BDB is usually always a male with an aggressive manly name such as Bronson or any other name in that category.
Dude that guy is such a BDB, he thinks he has a huge 13 inch dick but thats all he steals.
