Just like a "pothead" but this one is on Pokémon. Pokéheads can be found everywherethese days with their eyes glued to their cellphones. They roam around without a care in the world about where they are and how they got there.
The name for a person who decides to smoke incense (a.k.a. pulperie) rather than marijuana. Instead of "pothead", or "dopehead" it is "popehead". Idiots that smoke harmful incense, which is much worse for you than marijuana.
"Dude you are such a popehead"
"Those guys are such popeheads"
"He smokes that fake incense, he's a popehead"
