Sayfish

n. A sincere emotion that seems to wither into mush as soon as you try to put it into words--like reeling in a shimmering beast from the deep only to watch it wriggle limply on the line, which makes you want to leave it down there, languishing unexpressed, where it'll grow dark and slender and weird, with ghostly blue eyes and long translucent teeth. The sailfish is a species of fish noted for its violent power, its eponymous signaling fin, and its ability to change colors like a chameleon. It's also known as the boohoo.
