Some one who has a small head for their body size. Also can be characterised by a small jaw and/or large ears. Obviously, some one with a small head, receeding jaw and large ears can be described as "piphead extremis".
While watching the TV we noticed that the presenter was a Piphead. The more we looked the more obvious it became.
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"
