Gigafuckton
Currently the largest amount of any given thing. Many times larger than the fuckton, and vastly larger than a shitload or assload.
1 Gigafuckton is equal to...
1x10^3 Megafucktons
1x10^6 Kilofucktons
1x10^9 Fucktons

After not emptying the trash for 3 weeks, I found a gigafuckton of ants living in it.
