A beer blast to me in my opinion is a bunch of beer kegs and a whole lot of people parting with a huge supply of beer on tap. The more kegs the more people. Beer blasts can have a ton of people there. Usually collage parties, do this type of thing. I would not rule out younger kids trying to pull it off at a more low key place. So unless their are some new terms to things I am unaware of I would say you pretty much answered this yourself. :)
WARNING: Beware of funnel drinking, they might do things like that too at these parties. They take a funnel with a tube and chug chug chug...This can be very dangerous....
Ok well I guess thats about all I know as well, tell me if this helped at all.
