poi
Yuudachi from Kantai Collection's catchphrase-poi.
To be used only when there is particular emphasis on the phrase "poi" (when used standalone, "poi" is in romaji, a pun, etc...) and the use is related in some way to Yuudachi, not just as a comparative particle of sorts-poi.
Not to be confused with the festival goldfish scoop, the tethered weights (sometimes lit) used in the eponymous performance art, the polynesian staple food, or even the 3d adventure platformer game-poi.
