Donald Trump is one of the worst things to happen to humanity, so it makes sense that his joining of Twitter makes this list. When he's not rallying against President Obama, making ridiculous claims, or threatening to sue Complex's Man of Next Year, Mac Miller, he's being his usual ridiculously trolling self. Was there ever a time when Trump was cool, or nah?
On the other end of the spectrum is Chris Brown who just can't seem to realize that at this point in his career a diary or a therapist, or both, would probably be better for him that publicly ethering himself on Twitter. Brown's quit Twitter many times before, but we can't wait for the day that he hangs it up for good and sticks to scribbling idiotic things on body.
