A planned occasion at night which involves skanky ladies that would do just about anything to see some serious desperate meat compete for their stanky holes.
It's ladies night out so no meat allowed. It'll be a taco party,..minus the sour cream of course.

When all the girls in a group of friends go out, leaving the guy friends and boyfriends behind for a night of fun. -flirting with hott waiters to get free food is a must!
Last night we racked up $40 worth of free food at Casa Ole at girls' night out.

The act in which a group of old female friends go out without their old fart husbands. Old gals' night out usually begins slow with dinner and drinks at a restaurant. The evening picks up when the old gals get soused and end up closing down the local nightclub.
The ladies had an Old gals' night out and went to see the male strippers.

A boys night out, where most 'males' invite friends to have fun and look at porn. Also known as a 'BNO'.

A really lame thing to do. Most kids who think there 'cool' have one.
Johny: "Hey can i have some pornos for my Boys night out"
Friend 2: "wait what, you have a BNO?"
