muscle orgasm

When you work out so Intense that after you're done you lay down on the floor and this immense feeling of relief goes through the muscles which you trained. This feeling is very similar to the one you get after masturbation. Muscle Orgasm is the very reason why some people love working out.

The downside is that it will feel like Satan is Riding your back and repeatedly stabbing you while you walk through the Gates of Hell

One way of getting Muscle Orgasm is:
1 - set a timer for 3 minutes on your phone
2 - stay in a squatting position. Try not to move
3 - ONLY lay down after the timer hits 0 OR if your muscles can't handle it anymore.
4 - enjoy :)

muscle rock

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.*
