A guy who is CONCEDED and thinks he got good dick but really most people who said his dick WAS good lied. ONLY a few girls actually say his dick is good. LOL. Johnny boy... Not self confidence
Random cute girl: your dick is the best!

Johnnyboy: every girl says that about me!
Random cute chick: -.- you are conceded.
