pad wedgie
Your pad climbs up your butt like it has a ladder and ends up stuck in your vaginal crack. When you yank it out, it sounds like a crinkly snack bag that's been stepped on.
During lunch, my pad moved up my butt and I had to take it out in front of my friends.
My pad got stuck in my crotch during band practice and I had to rip it out in the middle of a song.
I was sitting in science class and my pad made a loud crinkly noise and my teacher turned around.
