My young lad used to leave the odd Fuck go, but seldom in my company, picked it up from his mates, or possibly my mother in law! I noticed about a year ago it stopped so i quizzed him. He replied i stopped saying it because everyone says it now and it got boring!!! and then he capped it nicely by saying, of all the words we have to use, fuck is the one that has no actual meaning! think about it what does it mean in fuck off - i dont give a fuck - no i fucking wont - or most annoying when they drop it into the middle of another word. eg its a tele-fucking-vision. Thus he now uses normal words. Yes i was quite surprised, and needless to say a little pround of my young lad (14)
