I've been posting some Queefcore the past few days in DUAN. Naturally, this has confused some members of the Deadspin Commentariat, who apparently never got the message about long-ignored genre. (I blame this on the fact that most Queffcore aficionados tend to be college sports fans, and tend not to mix as much with fellow sports fan brethren.) So after multiple requests, here is a quick and hopefully painless explanation of the Queef.
Queefcore is a term developed in 2010 by Spencer Hall in to describe what essentially commercial radio-friendly rock recorded by bands originating mostly (but not exclusively) from the Southern US (most notably Florida) in the mid-to-late 90s and early 2000s. This includes artists such as Matchbox 20, Sister Hazel, John Mayer, Three Doors Down, and (reluctantly) Creed.
Hall defined the musical style of Queefcore as "riff-free guitar strumming, baritone mock Vedder vocals sung with a glee club blues accent, and everything else as accessory." Basic guitar chords generally with a 4/4 drumbeat. Queefcore lyrics have been described as "clumsily emotional" to the point of being extremely literal. As Hall put it "If love lies bleeding in your hands, it may be literally bleeding in your hands."
Queefcore has also been described as being "aggressively yearning while maintaining a mellow quality," and trying to "to take a personal mood and make it universal." Queef has also been accused of being "douchebag empowerment music" due to the tendency of lyrics to be self-centered whether they were intended to be or not.
While Hall pinpointed to the late 90s as the gestation point of Queefcore, several bands from the early-to-mid 90s can also be said to be either Queefcore, proto-Queefcore, or to have basically devolved into Queefcore. The most notable groups in this category include Better Than Ezra, Colllective Soul (which arguably has a case for being the first true Queefcore band), Gin Blossoms, and the Goo Goo Dolls (the most obvious example of a band devolving into Queef).
Other notable artists identified as Queefcore on some level are Lifehouse, Vertical Horizon, Tonic, Sugar Ray, Third Eye Blind, Five for Fighting, most Christian rock/worship music, Fuel, and Train (described by Hall as " THE WORST QUEEFCORE BAND EVER" for having the audacity of actually getting lyrical.)
After three-fifths of a decade or so of pseudo-dominance of rock radio, Queefcore began either to fade as more harder, douchier artists such as Nickleback or Staind took over the airwaves. This has caused some confusion as to whether or not these bands were themselves Queefcore. The main difference between Queefcore and these artists is that the music is harder and the lyrics are more overtly douchy. This harder should be more properly name "Douchecore," and be handled as a separate case to itself.
