Just don't be an asshole about it

Yeah, see, it's not the first part that's the problem. It's the second part.

Put another way, if I walk around saying "Go fuck yourself!" you think I'm kind of a jackass, right? Now, imagine if I'm a jackass carrying a gun, or possibly carrying a deadly virus.

Yeah, see, a jackass that can commit mass murder!

And this is literally the problem with everyone laughing at this meme - they get so self-absorbed and self-congratulatory about the first part, they completely miss the part about how they're shouting to the world 

"I'm a jackass! You will respect me!"

Being a jackass doesn't make anyone special.

Doesn't work that way, luv. Doesn't work that way.
