The time when events go south at a bar or series of bars close to each other(Caroline Street in Saratoga Springs on a Friday or Saturday night) A time when fights break out, people get thrown through windows stabbings and even people getting shot. The timing is fluid, it can start anywhere between 11pm to 4am and happen multiple times despite a large police presence.

When someone is "unattractive". In reality it just means you don't meet the standards of what people call pretty.
