The Friday after Thanksgiving when you reuse all of the peanut oil you used to deep fry a turkey and deep fry other items. Including (but not limited to): tempura veges, fish sticks, cheese sticks, oreos, etc.
So, for the camping menu- everyone bring something for Fry-day.
Just another Friday spent frying on drugs such as mushrooms or LSD
"You got the goods for Fryday?"
"We're frying on Fryday"
The hottest day of the week at work when your boss floods your inbox with last-minute assignments so that your weekend is ruined.
My boss tried to ruin my weekend by piling on work last Fryday - but I made sure I wrapped it all up in time.
