A common after effect of marijuana. A state of mind in which you are not ready for any kind of thinking. Usually noticed a day after smoking when one feels "funny" or "confused".
Dude 1- Hey man, why is Wes asking me math questions from his homework? Isn't he a math major?
Dude 2- Yeah, but I think he's still a little bong phased from smoking with me last night.
