Okay so this happened in February.

I was sixteen at the time (I'm 17M) and it was about 4 in the morning so I'm up getting ready for school and preparing to walk to a different bus stop. I did this every morning for the past four months to keep a promise I made to my crush (that's an emotional tifu for another time). So I walk to her neighborhood which is exactly .9 miles away from my own. I wait outside of her place until 6:20 for her to come out then I walk her to her bus stop.

Sometime later

I'm in my third class of the day, Honors Spanish II. The class receives their worksheets, I finish my work while everyone is socializing. After finishing I staple my work together and then my friend points it out. “Epic_Sauce, I can see your underwear.” So then I blink a few times and hope that I'm just being pranked as I reach to the right side of my pants.....and cop of feel of my own right asscheek. [Insert buffering cat meme], I'm frozen for a few seconds then I'm laughing while pulling the flap that was my southeastern guard for my butt as I'm just hoping that I don't get a wedgie today. I spent the rest of the day being butt of my friends jokes while protecting my ass from view until I got home.

tl;dr: went to school and accidentally showed my ass through a rip in my pants
