Butt problems

Sorry if this is tmi but I used to love my butt I’m in highschool and recently my friend told me my butt jiggled when I walked she said I was thicc but didt elaborate on if I looked really bad. I do have a big butt so now I’ve been scared to wear leggings. It’s not that I don’t want anyone to look at my butt but certainly not if it’s too jiggly. IDK!!! I’m kinda very self conscious Rn
