Any dystopian landscape or system in which there is little greenery, fuel or humanity to be found. Named after the Mad Max series of films, anything madmaxian is
essentially a brutal, lawless hellscape likely filled with either bandits, raiders, and people eagerly executing their worst instincts, or bleak emptiness.
Colombia, Somalia,
New Mexico, and regular Mexico are thought to be Madmaxian - a
good place to be sunburnt, robbed, and possibly shot.
