someone who will say that they smoke (weed or cigs) and will allways talk about it and say that they smoke. They will actually bring some to school or whaere ever and tell every body that they have it,because no one who actually smokes will be such a dumbass to bring weed to school. They will also come to school pretend "high". You can tell by what they call weed or bowls, becase a poser smoker will call a bowl a pipe and/or weed dope.
"Hey Billy I got some dope"
"It's called weed dumbass"
"Well, look at my new pipe"
"Whatever fagot your the biggest poser smoker ever"
