DH bought a copy of the Beano for DD2 (age 6) - which had the delightful free gift of a "Fart Bucket" (squidgy putty to make farty noises) on the front and a wordsearch with different words for fart - air biscuit, bottom burp etc. Now I know that kids use this word, and I'm probably an old fogey, but I don't really see it as acceptable in print? I'd prefer good old fashioned trumps, botty burps, blow off, parp etc. I've explained to DD2 that it may be said in the playground, but I don't expect to hear her say it (in the same way that I'm sure teenage DD swears with her mates, but wouldn't in the house or in polite company). Interestingly it doesn't seem acceptable on Corrie, as last night a character said "I havn't got time to f-, er, break wind".
So, bring on the opinions and shoot me down for being an old fart (yeah, and a hypocrite, it's OK if I say it...)
