The supernatural ability that some women’s pussies have to grip a dick during a vigorous banging session. It will usually result in immediate jizzing for all but the most experienced men.
Pat: Was that broad you brought home last night worth another run?
Lee: She was like a unicorn using her magical superpowers of the 3rd muscle to grip my dick I lost it and filled her full.

A special kind of muscle that can only be created by a few men in this world. To grow the type muscle you must drink many many bud lights whether it be keg can or bottle beer, as long as it's bud light. The only twist is that you have to be born on valentines day. In this case all the bud light that's consumed will become Beer Muscle because of all the 12 ounce curls and the females love it.
"Check out that guys muscles. I heard he doesn't even work out."
"He doesn't, he just drinks Bud Light every day and developed beautiful Valentines Beer Muscle"

Similar to the Indonesian slang term "otot polos" with this same meaning, this tongue-in-cheek term referring to Deadpool's poor self-control, particularly in his tendency to swear and act impulsively. This phrase playfully implies that, like smooth muscle tissue, which operates involuntarily, Deadpool's mouth runs on autopilot, often leading to hilariously inappropriate outbursts.
I love how Deadpool is total smooth muscle—his swearing just pops out without a filter, making every scene even more entertaining!
