This is what my ex used to say before she started beating me. This isn't a feeling normal people feel.
I once read that the parts of the brain responsible for regulating "aww" and "aggression" are connected and may misfire when feelings are strong. So if you find something or someone incredibly cute or adorable, you may be consciously or subconsciously resisting the urge to destroy it/them.
I have a friend who used to... Might still playfully/crazily nibble on his kids. It doesn't hurt them, but he seems to have this going on in his head.
