A standard of measurement with no basis in reality. The phrase derives from men who exaggerate the size of their penis.

When you're having sex with a girl for the first time, don't insert your penis all the way in, leave at least an inch outside the vagina. So in the case that the girl asks you to "go deeper" you have some dick left to give her.
She's asked me to go deeper, lucky I still had my reserve inch. Phew!

I forgot to leave a reserve inch, when she asked me to go deeper I couldn't and she laughed in my face.

This term refers to a man "gaining" an inch to his dick by having done something extremely badass/manly, thus becoming even more manly. Men can wear these accomplishments as a medal and brag about them at later dates.
Dude #1: "Man yesterday was crazy! I definitely gained an inch."
Dude #2: "What did you do to earn that accomplishment?"
Dude #1: "I grew a beard, threw on my plaid shirt and bibs, and went out to the forest and chopped down trees to make myself a log cabin."
Dude #2: "Damn!"
