Fleeting expletive

A fleeting expletive is when someone says a bad word on TV or Radio, but only for a short moment. It's like when you accidentally say a bad word and then try to cover it up quickly before anyone notices. When this happens on TV or Radio, the bad word might slip out by mistake and the people in charge try to bleep it out or cut it off as soon as possible. This is important because bad words can be offensive and rude, especially if children are watching or listening. The people in charge want to make sure everyone enjoys their TV or Radio show without being exposed to bad words.
