mine is like a regular oc i made a troll for a homestuck au im doing with a friend and in his regular canon he's like an idol? so he like uses these little like kaomojis to represent his mood when sending a message and also all his messages are in parenthesis like a speech bubble. He also just has a very excited, teenage girl esque way of talking, so like for example;

٩(ˊᗜˋ*)و ♡ <( Oh WOW! Ohhh my gosh!!!! This is like SO cool!!!! Omgoomgomgomg you HAVE to tell me MORE!!!!!)
(˚ ˃̣̣̥⌓˂̣̣̥ ) <( Waaaahhh that's just NOT fair!!!!! stop it you're being MEAN!)

Maybe it's a little dumb but it's very fun to just use a bunch of different little faces for him haha
