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).

Slightly more than an Imperial fuck ton. The exact measurements of the metric fuck ton are unknown, owing to the fact that the term is generally used to describe an indeterminately-large quantity of something.

1) An unimaginable amount of something; so much of an object, item, or substance that it is so immeasurable it cannot be classified as a fuck ton.

2) A lot more than an 'Ass Load' or 'Shit Ton' or even a regular fuck ton.
