My understanding of the definition "guys night out" is lying to your/wife girlfriend about a trip to Las Vegas, going clubbing in your 30's with male friends, spending time at a topless swiming pool and spending lots of money on gambeling, alcohol and strip clubs. Oh~ and part of going this route of guys' night out is making sure that other friends and family members are "in on it" so esentially having them lie for the boyfriend/husband as well. Last thing, sharing a king-size bed with your BFF is also part of the guys' night out have a good time thing.

When a group of guys go out together sans female friends, and generally go wild.

(N.) When a group of guys go out for the night. The other "Nine to Five" that takes place between 9:00pm and 5:00pm, usually on Saturdays.

A typical guys (or lads) night out involves going to a pub or nightclub and drinking excessive amounts of alcohol (mainly beer/lager), shouting obsenities at members of the public, harassing members of the opposite sex and generally being obnoxious.

a night out where a bunch of guys set out to do something that their conciences won't let them do. the attached guys usually end up bailing out their single friend out of jail because he's the only one who actually had guilt-free fun!

The international code for "Guys Night Out".

Bro-night is a night when a group of male friends get together to do something in the intentional absence of women.

This is typically undertaken by a group of friends who are all in committed relationships, and wish to get away from womanly things, and eat pizza with their dude friends.
