Acronym that stands for “Weekend Of No Inhibitions”. WONI is a state-of-mind one must undertake during extremely fun “friend

only” weekends (Note: If significant others are involved then achieving the appropriate state-of-mind is virtually impossible). Pronounced as follows – wah-nee.
“WONI” can also be used to describe an extremely entertaining all-weekend event or a person’s particularly fun behavior at said event.
