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!
While a brilliant monster reveal in a film (e.g. Alien, Jaws, The Thing) is normally referred to as the "money shot", a bad monster reveal is referred to as a "coupon shot". Coined by RedLetterMedia in their reviews of the films Biohazard and Carnosaur 2.
"I thought we were gonna get a great reveal of the monster, but instead we get another awkward coupon shot of the alien just standing there next to a guy in the back of a truck" - Rich Evans
