Is there still some superstition surrounding the festival or is it just tradition now?

I'd say it's 90 percent tradition and 10 percent superstition. On the Monday of the event, groups of busós visit the locals. Hosts welcome them and offer snacks, pastry and drinks (mostly pálinka and mulled wine). If busós are welcome and offered such goods, they "help" the locals by bringing in good fortune and luck; whether it be childbirth, good crops for the next year, and so on. But if they are not welcome, they bring the hex to the house or become hostile. This can be mild like climbing on top of the fence, the house, or picking up the hosts and covering them in flour or sawdust. Sometimes they get more naughty and let the pigs, hens, roosters, and cows out. Some cause chaos in the households. In the past, many people used this event to take revenge on others for real or imagined issues.
