It's bad enough for someone to be ridiculed for what they're wearing on the outside, but 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 or when their pants split. This is usually 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.
- Men’s white briefs/Y-fronts, known colloquially as "tighty-whiteys," are often designated "nerd" type underwear; though they're commonly used as "default" underwear for men in much of media.
- "Granny panties" are the female version of tighty-whiteys.
- Underwear in bad condition, and/or ill-fitting.
- Skimpy underwear for men, unless they have strong muscles and nice butts, as well as skimpy underwear for women if it makes them seem perverted.
- Men wearing what is considered to be women's underwear, as well as vice-versa (unless a Double Standard is in effect).
- People writing their names on their underwear.
- Surprisingly girly underwear worn by girls and women known to be tomboys that ruin their "tough girl" image.
- Underwear with things written on it like "Lucky pair".
- Old-fashioned underwear that a kid is being forced to wear by their parents.
Like all fashion styles, this is also subject to the Popularity Polynomial, depending on what was in style when the work was released. For example, briefs made a small 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.
- Hidoku Shinaide: Nemugasa, like the Stereotypical Nerd he is, almost always wears the classic white briefs. The uncoolness of the tighty-whities is subverted however, because Maya, who Has a Type for nerdy looking people in general, develops a bit of a fetish for Nemugasa in tighty-whities later in their relationship, which gets explored in a side chapter.
- In Inazuma Eleven, before going to training camp in episode 24, Endou's mom gave him a pair of underpants that she wrote his name on (so Endou wouldn't mix it up with someone else's, including Kabeyama) which he finds embarrassing.

- Later in the episode, Chisato tries on some of Takina's boxers, discovering that they're much more comfortable than panties. She immediately gets discovered and ridiculed by Mizuki.

- In Bridget Jones, Bridget has to decide whether to wear skimpy panties which will look good when she undresses or control-type undies which are more likely to get her undressed. (She’s good-looking enough, being played by Renée Zellweger, but Zellweger had deliberately put on a few pounds so as to convincingly play a woman with some insecurities about the amount of junk in her trunk.) She chooses the latter but in a surprising aversion, despite some initial alarm at the size of the panties, her date is actually turned on by them.
- F the Prom: Cole is subjected to a Pants-Pulling Prank by a fellow student, revealing his white briefs, earning him the nickname "Tighty". Despite that embarrassment, he continues to wear them as a senior.

- In the direct-to-video film Deal Of A Lifetime, an agent of the Devil is trying to take revenge on a teenage boy named Henry Spooner by finding ways to humiliate Henry and make his life miserable. One of the ways he does this is by casting a spell that causes Henry to lose all of his clothes, except for his tighty-whities, in the middle of the school hallway. As dozens of students file into the hallway after class, Henry is at first oblivious as to why they are all staring at him and laughing, until he looks down and realizes that he is wearing nothing but his underwear, forcing him to run away in complete embarrassment. Oddly enough, Henry is seen in boxer shorts in other scenes of the film, but just so happened to make a "nerdy" underwear choice on the day that he would end up losing his clothes in front of his classmates.

Downplayed in that Peacemaker was not embarrassed at all to be seen in them, and the whole moment appears to just be a fanservice moment to get the attractive and muscular John Cena in as little clothes as possible, as there's a close-up of his crotch in the underwear. Also seems to double as Briefs Boasting.
