A fork of Rural Dictionary
An expression of great disappointment/anger. Literally, to fuck a dog.
I was happily going home to celebrate my birthday, but hong kan! I broke my leg!
Assuming a fuck lasts 5 minutes, and the speed is 20 thrusts per minute of 5 inches at a time and a penile cross-section of 2 inches squared, a fuckload would be 1000 cubic inches.
I have a fuckload of work to do, I'll go out another time.
