When a girl has the choice of having sex with a plethora of different men and she cant decide who to have sex with so she looks at their penises to decide.

Dennis decided to define what phallus was by tattooing it to the shaft of his penis, thus creating his dicktionary.

A dicktionary is like a dictionary but instead of words it lists women that a man has slept with and includes a description of her body and performance as well as listing all of the ways she is willing to have sex. Kinda like a sophisticated black book.
If I don't slow down I'm gonna need a second notebook to continue writing my dicktionary. In the mean time I think I will look up and repeat the l section again.

A noun that designates a self-proclaimed and public dictionary for people who find themselves funny. Mostly used for instant and private jokes between weird persons. Can be online, free and quite hilarious.
X. "Hey homie, i found such a motherfuckin' play on words while I was stone. Check that out, it's gonna be so amazing."
Y. "No no, dude, save it for the online Dicktionary, I want the whole world to laugh with us!"
