A name for a hardcore crew of party-goers who often arrive at drinking parties equipped with one or more bottles of Golden Grain (or Everclear) and some grape soda or similar beverage to mix with the Golden Grain.
The party was dying, we were drinking beer and running out, but then the grain train showed up and we partied our asses off and all got fucking HAMMERED!
