hahaha, I've been asked about my flailing hand motions while I beatbox... It's not even really a conscious thing... so it may be closer to a seizure than you think :)
wow, that's crazy... I couldn't imagine losing my sense of taste. I love beer & food waaaayy too much for that. I hope your friend fully recovered... & Coors light has to be one of the worst beers around... 2nd only to Pabst Blue Ribbon
