Her violently latching onto people's mouths and sucking their souls out
Those disgusting children at the start whose mother's probably let them drink alcohol
All those young extras who've probably never owned any of her albums
The celebrities being pasted on top having committed 2 seconds of their lives to this video
Rita Ora actually being there
Chris Rock
Katy doing her hard chick;} persona
Beyoncé being forced by her husband to take part to save his dying business
Her reedy ratlike vocals
That horrible farting breakdown
Nicki being the best thing about it, but only being present via Skype
The proplike appropration of asian women
Her desperate need to look young and trendy;] capitalised by those violent pink hightlights
The fact that anyone allowed this song to be created, let alone put on an album and chosen as a single
This being released via Tidal
Madonna really has the little monsters so bothered, like Gaga is way more cringeworthy anyway so 
there are so many things to laugh about that video
