A tactical vomit effected in order to continue a night out.
The seventh-inning wretch normally occurs between 11pm and 1am, when partygoers who mixed whiskey and beer or rum and wine at the pregame dash to the restroom to pitch forward and re-serve their dinner plate. The seventh-inning wretch is normally a solitary event but can also be a team effort.
When everyone decided spontaneously to go to a club after Neil’s pregame and the bar next door, I dashed to the facilities for a seventh-inning wretch so the bouncers wouldn’t see how plastered I was.
