Sheestee

Today I dropped my cell phone and said, "Sheestee!" (It is a word I made up and don't recall ever using it before.)

SB was near me when I said it.  She asked, "Why did you say sheestee?"

I said, "I don't know.  I dropped my cell phone, so I just said that word."

She said, "I know why you said it; because shit is not a nice word."

Yes, SB you are right shit is not a nice word!
