Sippy cup describes a story of the character cry baby and one day they'll see what goes down in the kitchen of dollhouse her mum gets drunk when her dad comes home with another woman so her mum wants to kill them and stabs them to death .Cry baby hears the noise woken up goes down to the kitchen and sees the bodies .her mum eventually kills cry baby to by making her drink "syrup " in a sippy cup. Sincerely Rebekah Brasiel
Adding on to that, I think that the verses are the perspective of the mother. In the first verse, she is talking about her husband and how it is dumb of him to think that she doesn't know what is going on. When she says "You call that ass your own, we call that silicone," the mother is talking about how fake the other woman is. In the second verse, I think the mother is talking about how insecure the other woman is about her beautiful self.
