People generally using incorrect Japanese in the middle of sentences.
I don't mind a cute hand gesture and "kira~!" pose, and little things like that but...
I have a friend who says "soshte" instead of "and". Literally replaces the word "and" in every sentence with "soshte".
...its "soshite"... and it's not used for saying "object and object"
star and snow
hoshi to yuki
NOT hoshi soshite yuki
DEFINATELY NOT hoshi soshte yuki
makes me want to cry...
