Cake smashing is my biggest pet peeve.  I told my husband I would divorce him that day if he smashed cake in my face on our wedding.  It's so disrespectful  You don't smash cake in someone's face that you love and respect.    And babies doing it.... don't get me started.  I walked out of my nephew's first birthday party because my fat fuck sister-in-law thought it was cute.  Food is not a toy.  Teaching young, impressionable babies to waste is not cute or funny or something to encourage.
