Lusus Naturae's definitions
A word describing a particularly masculine woman. Characteristics of a "big diesel" include large bisceps and a square jawbone. Probably derived from observed similiarities between masculine women and male truckers.
You may be one sick mofo, Edwin, but I'll bet "big diesel" over there can give you a run for your money.
