Does anybody know the title or the artist of this painting?

I recently went to the Carnegie Art Museum, in Pittsburgh, Pennsylvania. In the more modern art exhibits, I think around the 1950s-1970s, I saw one painting that I really liked. It was all words on a white background, and they were all ways to say goodbye, in a kind of ignorant matter. It was kind of like "goodbye, leave, fuck off, piss off, go away, etc, etc" and at the end it said something like "dont bother looking back just get out of my fucking sight."

if anybody knows the title or the artists name, i would really appreciate it.
