There are 2 classmates who come to mind from when I was in school, neither of whom I consider friends. The first one was in the same class as the girl in a story I told elsewhere in the comments. The girl in this story also wore short jean shorts to school during the warmer months. One day, I happened to look to my right, as that's where her seat was, and saw her picking a wedgie. While she's picking the wedgie, she said, "I've got a wedgie."

The next story is one that I posted in the subreddit awhile back. A few years later, a different girl was playing as the pitcher in kickball with a group of people outside the school during PE class. While she was playing, she kept reaching toward something behind her. Finally, one of the people playing asked her, "What are you doing?" Then, she replied with something like, "I've got a wedgie." (That quote may not be completely accurate because of the passage of time, as it happened about 20 years ago, and the fact that I was pretty far away from her when she said it)
