look up any word, like fleek:
people stereotype a pot head as anyone who smokes dope,weed,pot,grass etc.. But the correct definition of a pot head is someone who smokes alone. If you are with people it is perfectly okay to light up, but once you start relying on the dope, and light up alone, you are officially known as a pot head.

Someone who smokes a lot of weed. Most of the time they can function in society with no problem at all. They are successful people who just like to smoke weed. However there are always those people who smoke weed all day and cannot function. Those are called losers.

Pothead is not a term to be used lightly. You cannot start calling yourself a pothead until others do first. Its like a pothead rule man.

Potheads only smoke pot. Maybe a little shrooms but no hard drugs. If a pothead does a hard drug they move into the term "druggie" which is almost a complete opposite from pothead. Potheads are cool, druggies are quite lame.
"Dude, your such a pothead."

A word that annoying people who don't smoke and don't have the guts to try smoking marijuana used to define all marijuana smokers to insult them. However, stoners don't ever give a shit, and they know for a fact that people are just jealous of their carefree lifestyle.
Annoying bitch (looks directly at me while talking to some guys): I mean, who's not a pothead nowadays?
Me (listens to Wiz, obviously not giving two shits)
Annoying bitch (still looks at me): ME!!! I'm the only one who's not a pothead.
Me (yawns and falls asleep, continues on not giving two shits about her)
