Classic underwear reveal, usually accidental, and tends to be accompanied by the above rhyme in film. Generally involves StockUnderwear, especially GoofyPrintUnderwear. This trope is usually for comedic intent, catching a character in their most embarrassing state. There's also CringeComedy present, as the situation is usually awkward.
If revealing a character's underwear is used to defeat or incapacitate a character, see also DefeatByModesty.
