Ii des' yo! = It's good!

"Ne" (Neh) is sort of like saying "Isn't that right?". It's similar to the way some European languages use "Yes?" at the end of a sentence, like in German "Ist gut, ja?" = "Is good, yes?". In Japanese that would be "Ii des' ne?" (Ee des neh). It's OK for men and women to use "Ne", but using it a lot can be considered feminine. When a girl uses "Ne" a lot, it's considered cute and "Girly". If a guy says it too much, he might be considered a bit "girly" too. By the way, "Ne?" can be used by itself also. Since I brought up the thing about men and women, here's a few words that can help you sound more feminine or masculine. Instead of saying "Watashi" for "I/me", guys can use "Ore" (oh-reh), like "Ore wa Yattaro"="I am Yattaro", or "Boku", like "Boku wa Sukashi". Using a double word unnecessarily, like "Nani nani?" ="What what?" can be considered cute. But before you try anything out of the ordinary, make sure you know what you are doing first. The best way to do that is to listen to spoken Japanese, in person or while watching your favorite anime.
Boku wa Nyanki yo! = I am a Nyanki (Pizza Cat)!
Nyanki des' ne? = A Nyanki, right?
Sou sou (soh soh) = That is so (repeated to be cute)
That wasn't too hard, ne? Our next lesson should be fun, as I'll be covering some words that frequently come up in Anime.
