**Idk if this is actually NSFW because I'm talking about things that were discussed in a high school biology class but I thought I'd play it safe**

This happened to me back in high school and it's one of those moments that still passes my mind as being excruciatingly embarrassing. 

So a little info about me: I am a very sarcastic person. Not only that but to make my personality even more annoying, my sarcasm is often undetectable. I've been told even by close friends that they can't tell whether I'm being serious or not. Another thing to add is that, like most people, I usually say things without thinking. Okay I'm realizing now that these are all just excuses for what happened so let me just get on with my story. Oh one more thing that might not matter but I am of the female gender.

I was sitting in my high school biology class, bored out of my mind per usual. Focusing has always been super hard for me so I was doodling on my paper instead of taking notes (wow I have so many excuses for myself this is getting ridiculous). Anyways, I had no idea what the teacher was talking about and I was just scribbling away and probably thinking about what I was going to eat for lunch that day. So my selective hearing turned on when I heard my teacher say words like "full of mucus" and other gross words I can't remember. So since I thought I was being hilarious, still looking down at my blank notes, without thinking I said "yummy!". The teacher got silent so I looked up to see that she was talking about the contents of semen. My teacher was probably in shock and it took her a couple seconds to regain her train of thought before she continued teaching.
<bot>: I wasn't paying attention and class and sarcastically shouted out "yummy" when my teacher was talking about the mucus in semen.
