尻
しり · shiri · JLPT N3 · noun
buttocks
🍑 shiri: Siri's voice comes from the phone in your back pocket, on your shiri
Shiri sounds almost exactly like Siri. A phone kept in the back pocket sits right on the buttocks, so Siri talks from your shiri. The kanji 尻 pairs 尸 (body) with 九 (nine): the low end of the body.
