micturition n.

1725, "the need very badly to urinate," from Latin micturitum, from past participle of micturire "to desire to urinate," desiderative of mingere "to urinate," from PIE root *meigh- "to urinate." As during the final 20 minutes of a 4-hour film after drinking a 32-ounce Mountain Dew from the snack bar and the movie ends with a drawn-out farewell scene while Frodo is standing on the pier and wavelets lap audibly on the dock the whole time as if the director was a sadist set on compounding your torment. Also used, incorrectly, for "act of urinating."
