"Grand pianos crash together / When my boy walks down the street"

Do you have in your idiolect a specific term for "object of an infatuation"? In college most of my friends used "crushette" (regardless of sex) though I actually preferred "smit", which a friend created by back-formation from "smitten (with)". Nowadays I think "secret boyfriend/girlfriend" (i.e. so secret that even they don't know it yet) covers some of the same territory.

What about other languages? I can think of terms for the person who is crushed out (e.g. Spanish encaprichado) but none for the (oft unsuspecting) object of the crush.
