First, the backstory. Captain America became a superhero when he was given a supersoldier serum by the
army. He was immediately endowed with superhuman strength and endurance.

definition:
When someone is incredibly muscular that regular steroids could not have acheived such muscle size. Therefore, the person must be on the same
pills that Captain America takes.
"Holy shit have you seen jason's calves? the
kid must be on captain america pills."
"i
hate working out unlike captain america over there"
Kid 1- "he's so jacked if he makes a muscle it'll hit him in the eye"
Kid 2 "thats what the captain america pills'll do to ya"
