The event of getting blind drunk. A night (or longer period of time) on the booze when you get so f***ed up you can hardly remember anything that happened. Can be used in a similar context to bender.
Slang used in the West Midlands of England to refer to describe someone dressed dapper. Possibly the origin of the name of the Birmingham street gang the Peaky Blinders.
You're doing it doggy style....you spit on her back so she thinks you've cum....when she turns around, you blast off in her eye causing a "blinder"....
