What is 'gay Leather' Metal?
One who listens to power/heavy metal bands, which emphasise on "gay leather" themes* - lyrics, attire, etc.
*Typically fantasy depicted themes, but on their album covers, they're depicted as homosexuals in leather, w/ additional swords, and shields - something typical in an S&M homosexual pornography.
Manowar are a prominent 'gay leather' metal band. They're known for their S&M attires, 'gay leather' lyrics, which have redundant references to the word "sword".
