irony how?

Peeling her pants in the one place designed to prevent that from happening.

That's not irony or ironic. Being in a bathroom doesn't prevent someone from peeing themselves or help to hold it until in position . If OP ran there then suddenly lost all urge to pee once safely there - that would be ironic. OP had bad timing and their bladder just didn't make it in time it's unfortunate and poor judgment in their ability to hold it. Making it in the nick of time then accidentally splashing their pants while washing up and people thinking OP wet himself is good irony.

It can happen from the relief of getting there in time - it used to happen to one of my kids: you get there, think "I've made it", relax, and your sphincter lets go.

op never mentioned anything about a test.. they were in a lecture.

Or better yet, steal someone else's while they're having a shit.

Imagine the smell!

Was it a shiitake mushroom?

You've apparently never had the kind of professors I've had. I've had two different college teachers who would lock you out of the room if you left for any reason. I had to withdraw from the classes because they were docking me participation points despite the fact they were told I have a genetic condition that contributed to the frequency of bathroom needs. TL;DR There are a fair few professor that can and do power trip on their ability to make their students' lives hell if said students attempt to attend to biological needs, and some of them are big enough assholes about it to make students afraid to do so.

Those professors sound terrible. I have never had a prof be that strict, even if a class has a participation percentage, which only comes with certain classes, they still let us leave the room whenever we need. They can't even lock the door, because it isn't their individual classroom, they basically just borrow it for the class they teach. It's funny because I remember in high school they always used to scare us a lot about how strict university was with attendance and being on time, but it's the opposite, a lot of profs don't even care if you show up, at least where I live. In any case, those profs are ridiculous. This is college, most of us are adults and 18+, perfectly capable of understanding ourselves and our own needs. I think we can decide when we have to leave the room or not. They should be preparing you for when you leave college, and in the real world people or your boss generally aren't going to be regulating your bathroom activity.

I hate leaving a class in college because I feel like everyone looks at me which is very anxiety inducing.

Those professors are ridiculous, but that doesn't mean they don't exist. You just got lucky by not having them.

Did you report them to the dean? Everything else aside, refusing you bathroom breaks in spite of your condition is a violation of the ADA.

Ya, this is a definite ydi to me. You're an adult and should know when to use the bathroom. No one was forcing you to wait, you did that on your own. Next time just go and relieve yourself as quickly as you can and return to your seat.
