An adjective to describe a situation that is complicated and messy in multiple unpleasant and difficult ways. Similar to clusterfuck, except an adjective instead of a noun.
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).
When a situation, usually romantic or family, is messy, grueling, and complicated in multiple unpleasant and difficult ways. Also ultrafucktangular, megafucktangular.
That dinner with my girlfriend and her family was 8 ways Fucktangular ... it's going to take me months to recover
