n.; etymology: A portmanteau word <sl- (in slutty) and -unch (in brunch)>
a single meal that takes place between the hours of eleven in the morning to four in the afternoon and is intended to combine sluttiness with breakfast with lunch. Ergo, sluttiness + brunch becomes slunch.
Daaamn. We went out to slunch the other day with bottomless mimosas that degenerated into four loko pong and nobody remembers what happened or who won.
