I was told at work to stop using that phrase as it was wrong and I should drag myself out of the 70's. As I was leaving the office one of the commonwealth lads came up to tell speaks to troopy and informed him that he couldn't do the mil swim test as he "couldn't swim". Cue me sticking my head round the door and just looking at him then at the bloke and back to him whilst grinning like a loon. I was then informed by troopy to "fuck off now!" and he proceeded to berate the lad with "FFS of all the blokes in the troop you had to say it in front of him"
