Diaper shit

When a person in a discussion commits the error of their own ego or a fallacy of their own making that is harmfully influencing themselves, their perspective, or their own argument, to such an extreme degree, that they have a childish meltdown in their flawed assertion or argument.

You are taking a big diaper shit when you are constantly talking about how you are never given a moment to speak, and tell us in a whiny way, you are never allowed to speak.
