Macho: (adjective) masculine in an overly assertive or aggressive way.
Pablum: (noun) bland or insipid intellectual matter, entertainment, etc.
The name of this beer is a nod to some of the macho attitudes held by fans of old school bitter West Coast IPAs who had to have high IBUs and alcohol, and to one of the greatest bands of all time, Propagandhi, from where the expression “macho pablum” came.
