The show works up three freaking months just to censor the word "bitch" but so far they've only gotten to "b". So they would censor that whenever it comes along. Of course some fearers outsiders and overprotecteds fear to say the word "idiot" so they're final (and possibly first) loophole is "Bidiot". But they would censor the "b" so they would think they would say "fucking idiot" due to the sound of "*idiot".
Guy who's never seen the show: I was just watching (show) and all of a sudden a guy said "fucking idiot"! *other guy rolls eyes* He said Bidiot!

4.
an idiot who bids at the start of an auction, rather than waiting till the final moments, thereby driving up the price for everyone.
an item is on ebay with a start of one pound, a couple of people start bidding against each other from the start and drive the price up to £100 when there's still 6 days to go. The item would have sold for around that anyway but these two have made it not worthwhile for me to bid. These people are bidiots ... bid-idiots!
