Have you ever realized something super late in life that everyone else knows and that is, to be honest, kind of embarrassing?

We all have those moments, but only some of us are brave enough to admit them…

AskReddit users went on the record with their own stories…

1. It’s mint.

“That the phrase mint condition means like new because it’s the condition coins leave the mint in.”

2. Adults only.

“That when I was a kid and my dad would take me to the video store on Friday nights and he would go into the back room where only adults were allowed, that he was looking at porn.”

3. Walk the plank.

“I only just today realized that the “walk the plank” plank on a boat is not a special addition pirates added to their ships as a means of public execution that looked like a little wooden diving board.

It is, in fact, the very same plank as the gangplank you’d normally use to get on and off of the ship. It is not the presence of the plank that is threatening, but the absence of dock.”

4. Hahaha, that’s good.

“The first time I visited the USA I was on my own and in NY and going to all the museums. I kept seeing signs that said “No strollers” and thought, because we call strollers prams in the UK, that you guys are super strict about the proper amount of attention required to visit a museum. I actually pretended to show more interest than I had in order not to be thougth of as some deadbeat out for a casual stroll.

It wasn’t until about day three that I saw a “No strollers” sign that included a graphic for idiots.”

5. Not a compliment.

“That calling some one simple is just a nice way of calling some one stupid. Wife informed me of this, after 28 years of my grandma calling me simple.”

6. Wait…what?

“That you have to add a can of water to Campbell’s soup. Apparently I’ve been drinking straight condensed soup…”

7. That one took a while.

“I must’ve been around 11-12 years old, when I realized that “in order of appearance” during the end credits of a movie doesn’t list the actors/actresses by who is the most good looking.”

8. It has a timer.

“My boyfriend did not know that his electric toothbrush has a timer on it that goes off at 1 minute and 2 minutes. He actually returned it and got a new one thinking it was broken, since the “timer” is just a brief sort of pause/reduction in the vibration. He would be like “wtf I literally just charged this fucking thing” thinking that the battery was already dying.

One day, and I can’t remember exactly what the conversation was, I brought up how I liked that my toothbrush let me know when I had brushed long enough, and it was like a lightbulb went off in his head and suddenly he put it together that that was what his toothbrush was doing all along.”

9. Childhood = Ruined.

“That big ship’s wheel I got to turn as a kid was not actually controlling the cruise ship.”

10. I’ve heard people say this before.

“For the longest time, I always thought Prima Donna was Pre-Madonna.”

11. Genius.

“That parents have children write letters to Santa so they can figure out what to buy them for Christmas. I can’t believe how I never put that together after 32 years on this earth I just thought it was fun little tradition…”

12. That is kinda clever.

“It called Men’s Wearhouse and not Men’s Warehouse. It’s been a couple years since I realized this and I just think that’s a clever name.”

13. Oh boy…

“For a long time I thought “to bust a nut” meant that you were going to kick a guy in the balls or beat him up. So anytime I was getting worked up or angry talking about some guy I would say ” I’m going to bust his fucking nut” not knowing the real meaning. Nobody ever said anything but it was always followed by my friends laughing so I assumed it was because I was being dramatic.

Years go by and my coworker is telling me about some rude person he met and I said “you should definitely bust that guy’s nut”, to which he paused and said “do you even know what that means?” Suffice it to say I was extremely embarrassed and horrified when he explained it to me.”

14. When in Rome.

“Super embarrassing but in college I would order Roman Cokes because I heard everyone else ordering the same…turns out I misheard everyone and found out it was just rum and Coke.”

15. Never knew this! Wow!

“That they put measurement stickers next to gas station doors so if a robber is running out of the store you can get a better estimate of their height. I always thought they were just there for something fun to do on road trip stops….”
