cuff your jeans

The thing lesbians and other female members of the LGBTQIA+ community do to show that they are, in fact, a female member of the LGBTQIA+ community that can develop feeling for another female (who is not always a member of the LGBTQIA+ community and is usually their best friend)

*Could also be used as a metaphorical phrase that helps you let other people know you like girls, even though you might be wearing a skirt at the moment

Girl 1: Do you cuff your jeans?
Girl 2: Yea... Do you?
Girl 1: Yes, I cuff my jeans!

***

Girl A: Hey, I just wanted to let you know I cuff my jeans!
Girl B: But... You're in a skirt...
Girl A: Nevermind, that's not what I meant
