look up any word, like eiffel tower:
 
1.
A genre of music that could be considered a precursor to heavy metal. Sounds mostly like generic 70's hard rock (Foreigner, Foghat, etc) but imbued with fantasy, Norse mythology, and homoerotic gladiator themes. Has song titles like "We Accept the Challenge," "Steal Your Thunder," and "We Live to Rock."

The most well-known (and perhaps only) proponent of muscle rock is Jon Mikl Thor, who is also known for producing a string of terrible movies over the last 30 years.
Announcer: "And now, playing his 'muscle rock', is Jon Thor!"

*Audience goes quiet in disbelief as a 300 lb. beefcake runs out on stage in a sequined loincloth and cape.*
