Penis shelf is where you go to store your penis in the basement after you get married. A cold dark dusty shelf where things no longer of use are stored.
My buddy Freddie Goldheart used to slay so many gals , now that he is married his johnson is in the basement on the penis shelf
Now that I'm married I guess I will retire my johnson to the penis shelf

The byproduct of a masturbation session where your ejaculate flies from your penis with such force and ferocity that it lands on a distant shelf. The accumulated ejaculate can be compounded over time to form something similar to a Sploogy (an Emmy made of pure cum) or an Oskeet (an Oscar make of oxidized spunk).
Girlfriend: "Aww, that's cute. What's that award on that shelf!"
Guy :"Baby, that ain't no trophy. That's just shelf jelly."

When a man's dick is so small and feeble that it perches on his ball-sack acting as a shelf. Consequently, his piss runs down his balls before it reaches the toilet.
I dated this one girl for three months until she pulled down my pants and saw my shelf dick.
"Excuse me nurse..I do not know how to apply this catheter there are no instructions for if you have a shelf dick."
Bob: "Hey Ricky why do you sit down when you piss and it sounds like a leaky pipe?"
Ricky: "I was born with a shelf dick. If I stand up I will just piss all over myself."

Usually pertaining to guys, the friends shelf is when a girl labels you a friend, disallowing you to be anything more then "just friends".
I am on the friends shelf because this girl hangs out with me and we get along great but i will never be more then a friend to her.
