Complex - To be, or not to be thirsty: that is the question. Once a word primarily associated with wanting a beverage, thirsty is now used to express one's lustful feelings toward someone that you just can't contain. In other words, the modulated voice in Kanye West's "Mercy," isn't concerned with how parched your female companion is. He's just acknowledging how bad she wants sexual healing. We've all had our moments of thirst; sometimes they end up a success but most times they don't.
