a day of the working week where you choose to not work,kick back and relax. funday can replace any day of the week you want.

An extra day added to the week in an episode of Doug, created by slowing down the Earth's rotation, which is part of the weekend and probably the day after Friday.

A gathering of fanatical mountain bikers spending a day in the woods with hoppity hops (FunDay TM), food, frisbees, and of course bikes, making sick jokes in effort to laugh until accelerade comes out of your nose, and escape adult responsibilities.

the word FUNDAY basically describes.. an awesome day that is just ridiculously fun. FUNDAY is often used in cheers.. and can be altered to fit the activity.
