Cumbrian taxi driver
to "Go off like a
Cumbrian Taxi Driver" is another way of saying "to Go apeshit"The phrase originates from the 2010 case where taxi driver
Derrik Bird went on a murderous rampage through
Cumbria, killing twelve innocent people and injuring a further eleven. Apparently, the cause for his psychotic behaviour was a relatively minor annoyance - caused by drivers taking fares from the wrong end of the taxi lane.Typically speaking, "going off like a
Cumbrian taxi driver" is to overreact to a relatively minor annoyance, normally with extreme anger.
