Did she just use the "f bomb"?

Okay so this was about a week ago. You know the title of this post so you are probably thinking did Keigan say that 4 letter f word...well  DING DING DING you are correct she did! Okay so here we are Hunter is sitting on the fireplace while Keigan is sitting on my lap in his chair they are right next to each other. We where watching Taken (one of my absolute favorites since I am a daddy's girl). Well he is looking for his daughter and he is kicking ass man like hard core! He shoots this guy and at the same time Hunter and I go "BAMM whooo" and we start laughing...we said that because he knocked this guys ass out and we where impressed lol. Well as soon as we said that he got another guy....and Keigans exact and I mean EXACT words where "He just fucking killed that guy" <===== OMG right....so I had a smile on my face in which she could not see because she was in my lap and Hunter was right there trying trying trying not to laugh and he barely kept it together and he said "Keigy we don't say that word" She politely says "Uh huh we do" He says "No baby we don't and I don't want to hear you say it again okay" She says "Okay Daddy" so.....as of right now my child has gone about a week with out cursing it is a new record for her....its better then I can do I hope she can keep it up because I know I sure can't lol!
