More properly, "Metric Fucktonne." The Fuckton is the Imperial standard for the measurement of fuckweight, while the Fucktonne, in contrast, constitutes the Metric measure of fuckmass.

Generally used to imply superlative quantity with the Metric standard included to emphasise this point. The inclusion of the term is, however, fundamentally a misuse of that standard, as the Imperial Fuckton (2000 Imperial Fuckpounds) denotes a slightly greater measure of fuckweight within Earth's gravitational pull than does the Metric Fuckton (1000 Metric Fuckilograms).

A standard unit of measurement for amount. One metric fuckton is equal to 25 shitloads, a shitload is equal to 25 assloads, and an assload is equal to 50 of anything. By this logic, a shitload is 1250 of anything, and a metric fuckton is 31250 of anything.
