sex-core 

A post-hardcore genre of music involving down and dirty riffs with sexual innuendos and emo whines. Sex-core is a spin-off of fashion-core which involves wearing pants that are so tight they cause an automatic boner. Hence, sex-core. Often, large mo-hawks are considered a staple of sex-core and they can be used to impale the anus of other sex-core fans during the brutal breakdowns.
