Slowly figuring Paint Tool SAI out. xD
Lol, I looked at the title, and remembered my French teacher drilling our French II class on the sound -oi makes. Then, I heard a phantom voice whispering, "Wah, wah, wah, wah..."
Lol, that reminds me of one of my middle school band teachers (yeah, i played in the band xD) who used to try to get me to learn this one rhythm by saying "Ya Ta Ta Tah!" whenever it came up in the song. My friend still teases me about that. XD
xD That just sounds funny. It isn't even a language, just a sound.
