My two year old says it. I really don't think she's jaded or mature, and she has NO IDEA what the word means. All she knows is that mommy or I say it when we are Extremely Frustrated (and don't manage to censor ourselves fast enough). The worst part is, it's _extremely funny_ to hear her make a frustrated grunt, followed by "fuck!" We can't laugh, or we reward it!
