June 20, 2009 Urban Word of the Day
Arbitrary (and usually incorrect) units of measurement used mostly by males. 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 usually used when over-estimating non-penis measurements.

fellow two: "Yeah, only if you're measuring in dick inches."
