Alright, so let’s have an example. You might say that you’ve put your foot in it if you accidentally tell someone about their surprise birthday party. Or, your best friend told you have she’s pregnant, but that no one else knows yet, then you go off and spill the beans at Friday night drinks!
It’s important to remember that this expression is used when you say something you shouldn’t have by accident, if you do it on purpose, it doesn’t work!
So, can you think of a time when you really put your foot in it? I certainly can, that’s also why I don’t really like it when people tell me secrets!
