Your cousin, usually older than you, who smokes a lot of weed. If you don't have an older brother, it is likely that your weed cousin introduced you to smoking, and that he probably did it too early. Depending on geographical relation, a high-schooler may find himself at his weed cousin's house as often as once a month, and it is common to procure cannabis from the weed cousin until one's own supply becomes secure. Usually the son of a vodka aunt.
I was off with my weed cousin last weekend... He introduced me to dabbing. And edibles. I still can't think clearly!
