a unique name for a penis, not to be confused with a dingdong (doorbell), may be used in code when not wanting boys to know you are talking about their penis.
You could almost see his dillydong through his pants at the clublast night... or maybe I was just drunk....
A total douchebag. Loves being with his/her mom on any occasion. May excell in school but has no friends. Also may be someone who is horrible in bed. A disgrace to society. If you ever find yourself with this person, you know you are a fag.
