Pet word of British people. Favourite word of my professor. It is used as a synonymous to words like Shit or Damn. It is considered to be a vulgar word but with time it has melted into mainstream expressions to express dissastisfation. It was famously used in the movie '
If only'.
Many derieved words like 'buggery' or 'bugger off' are also commonly used.
'Ah! we just need to cut it a mm more to make it resonate at 415MHz'
(after cutting and measuring the piece again)
'This now resonates at 430 MHz...Bugger!'
