A Johnny derp fan
A person who thinks Johnny Depp is the only real person and will insult you with a level of rage that makes a volcano look like a toddler having a tantrum
'You're just a sad, brain-dead fan who can't even spell his name right!', said by someone who misspelled 'Johnny Depp' as 'Johny Dep' on a tweet.
'I'd beat you up with a stick if you weren't too weak to fight back!', said by someone who's never held a stick in their life.
'He's the only real person! The rest of you are just fake humans!', said by someone who thinks a 'fake human' is a nickname for a toaster.
