A Funny Frown is when you pout at someone for greeting you, but make it seem like it was a joke as an excuse to get away with being a rude cunt
Linus: hi Paige
Paige: *seriously frowns*
Also Paige: oh he doesn’t know me very well, I was just trying to be funny and he didn’t understand that.
Linus: funny frown 😡
