It could be a lot of things. If she's looking at you while doing it, she's flirting and having naughty thoughts of you. I tend to do it without realizing it if I'm in deep thought and I'll look over and see a guy smiling at me. That is really embarrassing when it happens lol
I was in maths and a really cute boy was there sitting across the aisle from our table and I noticed he was wearing skinny jeans so I said to my friend he wears skinny jeans then I bit my lip and looked him up and down I didn't know what it meant my friends just said I fancyed him
I like my guy best friend and he likes me but his mom won't let him date anyone so we were Just hanging out at a park and he bit his lip then I bit mine but I bit mine because I was thinking about if we kissed but we r still friends 😊 but I have no clue and Ik his more my lip were chapped just think if he/she bites her lip they are thinking about u
There's this guy that I have a crush on, but I'm not sure if he likes me or not. He jokes around and teases me and I would catch him staring at me a few times. I stared back at him without looking away & we held our gaze to what seemed like the longest time. Then I tried to smile back, but I was so nervous I just bit my bottom lip out of nervousness. However, sometimes I bite my upper or lower lip because my lips are chapped.
