Oh how the language is ever being tested and changing. Even our immutable standard unit of measure is now being qualified
Being one who was never able to max out when it came to endowment stakes I am please the Urban dictionary has added a new word to our language
Dick Inches is arbitrary (and usually incorrect) as a unit of measurement used mostly by males. It derives from men overestimating their penis size.
Dick inches are much shorter than actual inches. Hence a guy can claim to have a 9 inch penis when it is actually closer to 5-6 inches.
The term "dick inches" is used often too when over-estimating non-penis measurements.

fellow one: "There's plenty of room."
fellow two: "Yeah, only if you're measuring in dick inches."
