My Little Pony: Friendship is Magic - Image #280,014

Can someone please explain Dolan to me?
What is the appeal?
What's the joke?
It feels like it's supposed to be one of those 'it's-so-bad-it's-funny' kinds of things but it's really just not funny, on any level.
The worst jokes are those that garner no reaction and I just stare at these things, stone-faced, every single time.
…or is that the point?
Some massive trolling thing where everyone pretends to get a joke that doesn't actually exist just to confuse newcomers?
I just don't know…

Why all the downvotes? Clearly Rainbow Dash had the last word here.
