Well, for starters, this isn’t the correct topic for that kinda question.
Ask HMF anything might be better for that.
But, to answer your question anyway: I don’t think he has? After a quick google search, I don’t seem to find anything related between Pewdiepie or playing Hitman 3. I don’t think he does the whole playing games anymore.
It’s probably a little reference his editor snuck in instead.
