A fuckton is 2000 dry hump pounds or 2k dh lbs. Since dry humping requires the same effort of force and resistance to gravity as lifting any amount of ass mass at 1.0 g at sea level as free of ass mass does at 1.0g at sea level scientific conversion of fucktons to metric fucktons uses the same conversion constant value as tons converted to metric tons. In the United States if you put a metric fuckton of wet clothes in a dryer rated in regular fucktons at sea level your clothes will not dry in the specified amount of time for said fuckton value. You'll just be dry humping for much longer than you estimated...
"I knew I shouldn't have put a metric fuckton of wet clothes in the dryer.. It's only able to handle a single fuckton. I'm definitely going to be dry humping it out the door now."
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).
I've got a Metric Fucktonne of this stuff to finish before Monday, or I'm fucked indeed.
