Comes from "real" and "literally." Invented to compensate for the dramatic over- and mis-usage of the word "literally." What people now say as literal will usually not actually be literal, so the word "reliteral," or "reliterally," was invented to actually mean literally, and present no confusion as to whether the statement is actually literal or not.
"I swear, I literally have like four million cats." (misuse of "literally")
"I reliterally have seven cats. I can name them if you want me to." (correct!)
"Oh my god, I willlike, literally have ADD if you don't stop talking." (misuse)
"I reliterally have ADD, I just found out from the doctor today." (correct!)
A hardo is a person who tries extremely hard at everything. Most times a hardo will try very hard at things that do not require excessive effort. For example, sports practices, gym class, etc.
Wow did you see Jack at practice today? What a hardo!
