The Unclarity of Fought

I need better words, words that mean exactly what they say they are. For instance,I've told you to "fuck-off," in play, and I've said "goodbye," as you were heading out the door to the market, but I could have used both of those words at other times, times that weren't so fun. Maybe it's my fault, maybe I should reserve certain words for the exact moment and situation that I need them for,and just maybe I will keep the word I use for you, such as your name, separate from the word I use for a certain body part of yours that I at times enjoy.
