I mean, I think retarmus means that something is so retarded that you can't pronounce retard right because that thing is so retarded that it made you retarmus. That's what I think of when I call something retarmus, at least.
Bro, that girl thought that Christopher Columbus was the first US president. Bro, that's so retarmus.
