Definition of Girl's Night Out: ( girl's [gurl's] night [nahyt] out [out] )
- a night out with the girl's that includes extreme laughing and "dishing" (and man there was some good stuff last night)
I think there should be a specific day of the week that is the official GNO day. I laughed so hard last night, I'm pretty sure I worked out my abs. Is it sad that is the most I worked out this week? Don't answer that.
