Maybe not a misused phrase, but I hate it when people don't understand hyperbole. Maybe a sandwich doesn't warrant the word "enormity," but if someone says that it is then it's hyperbole.Kieran Villoth said:Enormity. People think it means 'a lot of something'. It actually means a 'outrageous or heinous on a grand scale'. The holocaust was an enormity. Your sandwich is not.
That said, I hate it when people use the phrase "literally" as hyperbole. EG, "My sandwich was as big as a whale!" (Acceptable hyperbole through simile). "My sandwich was as big as a whale... literally!" (Unacceptable hyperbole through the use of the word "literally").
Also, if someone said Pis-zah when they meant pizza, I would laugh so hard. What makes it funnier is that the guy actually has the nerve to call out everyone else for saying it wrong when he is clearly incorrect.
