the act of going big no matter what the situation is. Usually people who get full hard do so with a can of bud light and a fifth of fireball. Also no one knows if fullhard is one word or two.

Rule 1.1 No matter the situation always get fullhard
Word used to describe someone who has unrealistic ideas about how much remaining fuel their car / boat / barbecue has.
May also be used to describe someone who fills up their car at the exactly the most expensive point during a weekly price cycle or before busy public holidays.
Yuk... these sausages are still frozen in the middle
I know -- but they'd be fully cooked if your Dad wasn't so fuelhardy with the BBQ gas.
Damn... the prices have already gone up for the long-weekend. I could have filled up the car yesterday for $15 less!
Yes, but you were too fuelhardy.
