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
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.
