It's bad enough for someone to be ridiculed for what they're wearing on the outside, it's somehow more insulting to be teased for what you're wearing underneath.
This trope is when a character is teased for the kind of underwear that they are wearing, causing much embarrassment. There's any number of ways how what they're wearing under there can be known publicly, but it's usually revealed in a Pants-Pulling Prank. This is always Played for Laughs as the character teased just walks away with a bruised ego most of the time.
Types of underwear that end up being the target of this include:
- Goofy Print Underwear, usually of any style especially if they have a childish print, such as cute cartoon characters.
- White briefs/y-fronts, known colloquially as "tighty-whiteys," are often designated the "nerd" or "dad" type of underpants, and sometimes are meant to imply immaturity.
- "Granny panties" are the female version of tighty-whiteys.
- Underwear in bad condition, and/or ill-fitting.
- Skimpy underwear for men, unless they're confident about it.
- Men wearing what's considered to be women's underwear.
Like all fashion styles, this is also subject to the Popularity Polynomial, depending on what was in style when the work was released; briefs made a comeback in the Turn of the Millennium as the skinny fit jeans/pants rendered boxer shorts almost useless (and possibly helped by one Walter White) and character-printed underwear has come back with the rise of nerd culture in The New '10s. They even make underoos for adults now, we kid you not.
