(British)

To leave, go away. Nearly always used as an aggressive exclamation or instruction. A vulgar term that existed in armed-serv- ice use before becoming a vogue succes- sor to naff off around 1980. In spite of the brusque nature, the phrase is not taboo and is used by women.

'If he's going to treat her like that he can just bog off.' (Recorded, secretary, York, 1981).
