     …Oretachi? Masaka… omae mo koko de tachishonshita nin…gen?

     …We? Hold on… did you pee here when you were hu…man too?

     立(た)ちションじゃない　ウンコだ

     Tachishon ja nai unko da

     It wasn’t pee, it was a dump

• An informal and somewhat childish word; compare the more formal 大便 (daiben).
• While うんこ (unko) is sometimes given as a literal translation of English interjection shit! as an expression of displeasure, this is inaccurate, as unko! sounds more like someone saying “Oh turd!” or “Oh doo-doo!” in English. Rather, the vulgar くそ (kuso, “shit, excrement”) or the less vulgar ちぇ (che, onomatopoeic interjection of displeasure) may be used, while the most common expression of displeasure is しまった (shimatta, “oops, uh-oh”, usually when it is one's own fault).

うんこする • (unko suru) suru (stem うんこし (unko shi), past うんこした (unko shita))

1. (childish) to poop, to poo, to go number two

• うんち (unchi, “poop”)
• 糞(くそ) (kuso, “shit”)
• 大(だい)便(べん) (daiben, “stool”)
