You must specify!
You can't censor the first part of 'metric ****load'. It's essential to the unit - You wouldn't say that someone bought five ****meters of Cat5 cable!
So, for reference, the 'load' sequence*:
buttload
assload
shitload
fuckload
You can also have other prefixes than 'metric' as a further modifier:
metric buttload
ever-loving shitload
unholy fuckload
You should also be aware of the final, ultimate descriptor. I will be impressed when Nintendo sells an:
ever-loving fuckton.
There, see? That was easy.
*It should be noted that 'cuntload' and 'twatload' are highly inappropriate and should never be used.
