Help me translate & identify this mug

i found these at an estate sale. they're on page 103 of TQ, but not any other info. I flunked out of Chinese School ~ so i'm no help deciphering this (i'm not even certain this is chinese) can you help? what does this say..and where were these mugs used?

something about putting somethin in your butt. i wouldn't drink from those.

(it says "kabuki", it's japanese.)
