Labia Fingers
When you pull out some flabby skin from the crotch region and squeeze it between your fingers like you're trying to make it look like a monster’s hand. People take pictures of this and send them to their crushes like it's a love letter.
My crush sent me a labia fingers pic. I replied with 'is that your hand or your crotch?'
My brother sent me a labia fingers video during math class. I got in trouble for laughing too hard.
My friend took labia fingers and put it on Instagram. It got 5 likes and 3 comments that said 'what even is this?'
