Panchira (パンチラ?) is an expression used by Japanese women to warn each other that their underwear is visible; the term carries risqué connotations similar to the phrase "your slip is showing" in English usage. The word is a portmanteau of "panty" (パンティー pantī?) and chira, the Japanese sound symbolism representing a glance or glimpse. It differs from the more general term "upskirt" in that panchira specifies the presence of underpants (the absence of which would more accurately be described as ノーパン; nōpan).
