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!
