Rontard 

When someone is doing a job they have no ability or qualifications for but like to tell qualified people how to do their job.

That idiot was telling me how to do my job like a real rontard.

Rantaro

Meaning a character that 100% deserved better than what they ended up getting.
"Rantaro" is often used to refer to a boy with light green hair and a hot body. The boy often also radiates "fuck boy energy", although they are sweeter than it seems at first.

Person: Omg, I just finished the show and the protagonist is a total Rantaro!

Person: Why are the Rantaro characters always so hot? It's not fair!
