A formerly muscular but now just an old and flabby dude who deep down inside is nothing more than a jealous ass good for nothing snitch. So jealous that he goes to outlandish lengths such as driving by your house after dark like a punk, just to see if there’s anything he can run back and snitch/report on you for.

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!
