When a group of women get together to complain about men, problems with men, or the lack of men.
Usually involves acting in a manner in which any man who sees them would sever all ties with said women, should that man know them.
Things were going great with Mark until Gina and her friends went on a girl's night out.
Mark saw Gina at a club and slit his wrists in the bathroom.

Get the girls' night out mug.
A night where "girls" go out with their friends. The single girls in the group complain because the married ones are being hit on by the "hot" guys. The married girls are doing things with these hot guys that would be grounds for divorce, and overall they all get too drunk to remember why they are missing their panties and/or a chunk of their hair. Good Times!
Stacy had a girls' night out 9 1/2 months ago, and now her baby has red hair.

Get the girls' night out mug.
A night of partying with only females, that entails drinking heavily, acting silly, and checking out boys.

Often used as an excuse to get away from one's boyfriend...
John was being such an asshole that I really needed a girls' night to help clear my mind and put our relationship back in perspective; after a night of drinking and sillyness we decided that it's time that I dump him.

A night where girls get together to gossip about everything, gossip about their relationships, watch boring movies about love and romance, discuss fashion tips, discuss their evil plans of controlling their boyfriends/husbands, or simply find an excuse to talk for no reson whatsoever.

Get the girls' night out mug.
A night when a girl goes out with only other girls, when she claims that she is "bonding" with her fellow females. What this really means is they all get dressed up as sexy as possible so they can get hit on/meet as many men as possible, because as we know girls in large groups get noticed a lot more than girls by themselves.
Baby, don't worry, it's just a girl's night out.
