Skirmish
A gathering or social occasion, particularly a night out with friends with an unwritten agreement that the scope of the occasion’s festivities will be limited thereby leaving the participants able to function with a reasonable amount of alacrity in the morning. Mostly commonly used for midweek drinking and people’s whose lifestyle involves constant weekly partying.
Example:
John rang up to enquire if Jenny was coming out clubbing tonight.
Jenny replied "Yes, but it'll have to be a skirmish I've got to work the next day".
