Swarm the house?

My parents haven’t even packed more than six boxes and they’re already talking about something called a House Swarming. Holy crap, my fellow inebriates, I have no idea what to make of this. What does it mean? What the hell is a House Swarming?

Will the house be swarmed with people depositing things (liquor?) or removing things (liquor?)…

Or does it have anything to do with liquor at all?

Thoughts?

What's your poison? Drop me a line.
