Fatty

I pretended to be mad on principle, but he was so befuddled that I couldn't hold it.

Panel 1
Alex: Hey!  There's a lump here!  See, push your hand across it.  It's firmer than the sides, less fatty.

Panel 2
Beth: Less what?
Alex: Fatty.

Panel 3
Beth: Less WHAT?!
Alex: Fatty?

Panel 4
Beth: LOL  I'm pregnant, so maybe you should use a different word, like "squishy."
Alex: Oh!  I'm tired.
