DON'T CALL US GIRLY GIRLS. OR GIRLY.
Seriously. Like... yeah. It's not an insult, because being a girl is not bad, but it's like telling us that you get to dictate what we are? And...yeah, we usually know how to castrate you with a rubber band, so perhaps not a good idea to puss us off with a guy.
If you're a girl...I love you, sisters, but please don't. It's like you getting called a guy. Not bad to be a guy, but a wee bit insulting.
