oh man good thing I wasn't the only one puking my balls off when trying Outkastt famous butter... what the fuck does that shit have in it... its soo stong i still have some around holly shit....I have actually not only had nausea, but full fledged vomiting, from having 'too potent' butter. To answer your questions, it was no more butter than you would regularly put on toast, and there was no plant matter. Outkastt makes the best butter!
In fact, I don't want to blame is on stomach trouble at all. I got sick for much the same reason I get sick if I drink to much - everything was out of balance. So, probably more on the order of motion sickness, than an actual physical reaction in my digestive system.
But it certainly was a result of the potency of the butter.
Better believe that next piece off toast had just a skim of butter on it
