Uvula! ..According to my older sister at least! I was 18 and she was 21 at the time on the way to my parents house (I can't remember how the conversation led to me saying it) But I said UVULA! (Mind you not in a dirty/negative way/tone/etc) she shouts "GINA!!!" with a shocked and appalled look on her face and I said "what??" She said "Don't say things like that!" and I said "don't say things like what? I don't see anything wrong with saying the word uvula" she cringes and tells me I shouldn't. I said "Why?" and she said "Because it's a bad word!" I said "No its not do you even know what a uvula is?" She awkwardly stuttered out "No. I don't think i want to know either." I said "Do you want to see it?" she goes "No!!!" and I opened my mouth and pointed at it at the back of my throat as she cringed and covered her eyes freaking out and I said "it's the little thing that dangles in the back of your throat" (So she knew what I meant) and she went "Oh.." then she asked if I was sure that was the name for it and I said yes Her: "Well..Don't say it anyways" and I said "Why?" and she said "Because I don't know it just sounds wrong just don't say it people might take it the wrong way."
