So there's this word "runessaan" that I don't know, but apparently (according to Google) it's frequently used. Must be a slang. I don't know it. Maybe has something to do with the Renaissance?

"Umm...uhh..."
???? Something about runessaan and a kanji that is too small for me
"Nice to meet you. Shall we talk?

I think this says "I hate a man with no possessions" 品のない男は嫌いなの。じゃあね But it's too small for me, and I don't think は嫌い is proper grammar, which makes me think I'm wrong. And also having the な there makes my translation wrong, too.

Heh. I'll go out with you a bit. [the あ・げ・る is said in a teasing way that is untranslatable or at least I don't care to spend time thinking about a proper English equivalent now]

Die you fiend! [I read this as 一片死んでこい, if someone wants to correct me]

品 here means 品質. "I hate a man with no class" would be a better translation. Nothing wrong with は嫌い.

It is "Renaissance". It's the "in" phrase right now, spread by the stand-up comedy duo named 髭男爵（ひげだんしゃく） who are always dressed as old European aristocrats. They say ルネッサ～～ン（ス） all the time to mean "Cheers!".
