Oops, someone is not happy that other people are doing his work for him, it's true though, it must feel awkward to see others announcing your movies before you yourself. There is an easy fix of it though, announce it yourself, don't stretch it.
And in other words, those people under that tweet saying take your time, don't worry or we will wait..... F off, go shove some bleaching powder up your @$$ and disinfect it you vile creatures.
