Bring Your Own Fun

It means BYOB but fun is substituted for booze. This is done because alcohol often starts the fun. The lone Sober person at a party does not usually have any fun.
Fun is also substituted as a code word so that minors don't have to worry about adults figuring out what is going to go on at a party.
The fact that it sounds nerdy and innocent makes it ironic.

Bring your own fun to the party saturday.
Should have brought some fun.

Family Fun Night

The act of having 2 siblings have sexual relations with a man of the chinese ethnic background while fully intoxicated wielding a whip, spiked dildos, and of course... double-sided anal beads.

Me and my sister, April, had a darn good Family Fun Night with our good friend... Hu Flung Poo.

fun boy

A character from the movie "The Crow". The character was a bad ass, sex obsessed drug addict which displayed dark humor on occaision. All these other stupid urban dictionary posts are referencing gay men, which is a complete joke. Watch the movie, fun boy has been referenced since The Crow was released in '94. Quit clogging up the site with false info.

Fun Boy's got somethin' for you to play with.
