First I thought it was just a simple witty canned response ala Han Solo, and got confused of why we were elevating it to the level of joke that required to be understood by someone intelligent.

Then, as a non English native speaker, I thought it was a word play ("you have had a bad Phil o Sophie ass" + "I had too many" or something).

Then, reading the responses to your comment, found it was the witty canned response I originally thought all along...
