I don’t think 
is a very good emoji, because maybe the facial expression is there but it’s small and dark, and looks like a guy making a slightly-scrunched-but-essentially-neutral facial expression. A WTF emoji should have a big extravagant expression
I assume they were talking about the Jackie Chan meme.
Oh. Yeah, rereading it, I guess I’m not sure which they’re talking about for sure. It still seems like they meant the Jesse-Wtf one, given the comment they were responding to, and also since I don’t think that Jackie Chan image was ever really a meme, let alone popular. But I could be wrong. TrashcanOfIdeology, If you mean the Jackie Chan meme is 2000’s era advice animal, then my mistake, it could well be.
No worries, I was talking about the jackie chan meme being old and long irrelevant except to those of us who were terminally online in the 2000s, but I can see how you could’ve assumed otherwise from the way I wrote.
