The Secret Santa ritual is perhaps the most terrifying for those with poor shopping skills. Not only do you risk buying a bad present, but you're in competition with everyone else in the group who's going to look better than you. Your giftee's happiness is completely reliant on your skills in transforming their personality into physical gift form. Remember kids, if you don't know what to buy, get that jelly slime. Everybody wants to see someone open that and freak out.
