Politically correct yet still insulting version of "Retarded". Refers to people who are not mentally challenged but act like they are.
A person with Down's Syndrome is not Stopa but most political extremists are.
Created by online malcontents as a response to mental health groups requesting the word "retarded" no longer be used. Stopa replaces the word "Retarded" in insults. Because "Stopa" is so short, it also works as a replacement for "re-re" as a shortened version of "Retarded."
Jesus Christ that politician is such a Stopa!"
"That's Stopa grade stupid."
"You are Sooo f***ing Stopa."
"What are you, Stopa??"
