This phrase is used to describe most of the novels published by Black Library, Games Workshop's literary division. It indicates that a book possesses little to no intellectual reading value, instead consisting primarily of lurid descriptions of large-scale mayhem and carnage as carried out, typically, by the setting's iconic Space Marines and their spiky-armored opponents, the unironically-named Chaos Space Marines, as well as other colorful factions that occupy the planet-wide battlefields of the 41st millennium.
Space Marines, also known as the Adeptus Astartes, are cloistered chapters of towering, genetically-convoluted super-soldiers that thematically resemble medieval knightly orders, ascetic monk brotherhoods, mythical figures such as the Norse einherjar, and other classical warrior archetypes.
A "bolter" is the Space Marine's standard-issue weapon: A .75-caliber fully-automatic cinderblock-sized machine gun that fires self-propelled explosive ammunition.
The total ubiquity of this insanely destructive weapon, as well as other standard Space Marine affects such as chainswords (as in, swords that are chainsaws), says a lot about the tone of Warhammer 40,000, or simply "40k", a sci-fantasy tabletop miniatures game that has spawned a multitude of novels and other spinoffs, it's tagline: "In the Grim Darkness of the Far Future, there is Only War."
A lot of bolter porn is kind of awful.
Christian Z. Dunn's novel Pandorax, which was released in the UK in 2013 and North America in 2014, is bolter porn. But, it's not awful at all.
In fact, it's pretty great.
Grab a drink (I recommend the blood of heretics or tears of the damned), hit the jump, and I'll tell you all about it.
