But I'm chiller with the Miller - cold coolin' at the bar
Miller Brewing Company, founded in 1855, is one of America’s largest breweries. (In 2008, it merged with Coors Molson.)
The specific references to “cold coolin'” etc. might be a reference to their product Miller Genuine Draft — introduced in 1985, it was the first mass-produced beer to be cold-filtered (i.e. the filtering process is done at low temperatures, as opposed to most filtered beers, which are pasteurized by heat.)
But that might be reading too much into it.
