It's in the post title. You'd have to actually watch the video to get the reference, though.

'cum panda' is a pizzagate related term, used to describe a small child with TWO black eyes from severe anal rape. A 'pedo bear' is the cartoon character popularised on 4chan used to represent pedophiles.

I just find it odd that those precise two archetypes found their way into a popular pop video, but I'm sure it's just a coincidence.
