To lose really badly in a race, usually as it applies in motorcycle and car racing. Someone who has been gapped has lost a race so badly that he or she should strongly consider finding a new hobby.
Beating someone by half a car length is not a "gap." You must beat someone by an absolutely humiliating distance, like two or more bus lengths.
Joe thought he could take on Greg's corvette, but he got gapped and everyone saw.
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!"
