Definitions
A Japanese loanword used in ACG (anime, comics, games) communities and internet slang to mean panties or underpants — specifically women's underwear in the context of anime and manga fan culture. The word is a Japanese phonetic borrowing of the English 'pants' (in British English, underwear). In fandom contexts, it carries playful or titillating connotations associated with fanservice tropes in anime. Widely recognised among Western anime fans and used in fan discussions, fan art captions, and memes.
The episode's 'accidental' pantsu shot had the fandom debating whether it was deliberate fanservice or just bad camera angles.

Comments
(ACG, internet slang) panties ; underpants.
"pantsu" is internet slang meaning panties ; underpants. It travels through TikTok, Discord, Twitter/X, gaming chat and group DMs, and most teens absorb it from feeds and memes rather than from face-to-face friends. Using it is normal online-native behaviour and does not on its own indicate anything worrying. If you are not sure what they mean, asking them to explain it is a friendly, low-stakes way in; teens generally enjoy translating their corner of the internet for a curious parent.
"pantsu" is online-informal English meaning panties ; underpants. It is used widely across English varieties. A more formal or neutral equivalent would be something like "panties " expressed in standard vocabulary. A common mistake is to use "pantsu" in essays, emails or job applications; it belongs only in chat, social media or casual messaging. If you are a B2 or C1 learner, it is useful to recognise this word when you hear or read it, but think carefully about whether the situation really calls for it before using it yourself.
