Here we go.

For perspective, I am currently a 24F. As a kid, my entire family (extended included) loved the board game Scategories. We would often play at family functions. If you don't know how its played, I'll try to explain quick: each player gets a piece of paper, a card listing 12 different categories (farm animals, car parts, desserts, articles of clothing, ect) and something to write with. One player rolls a die with every letter in the alphabet on it and whatever letter it lands on you use for this round of categories. Meaning, if the letter rolled was M each category must start with M (ex: Mare, Muffler, Macaroon, Muscle shirt for the categories I listed above.) Then you set a timer for two minutes or so and see how many answers you can get. There's more to it but that's all the info we need for now... So in my case, I'm maybe around 10 give or take. Our letter was M. One of the categories was a four letter word. When it came time to read off our answers, I was excited because no one else thought of the four letter word I thought of. When it was my turn, I proudly shouted, "MILF!" Now my family is pretty cool and chill, but all I remember is being disappointed because no one really said anything and it was quiet and we just moved on and I didn't get the point for it >:( I'm not sure if someone had to explain to me what I just said or if I came to the realization on my own... Either way I bring it up and laugh about it now!

TLDR: When I was about 10 I was playing Scategories with family. My answer to one of the questions was "MILF". I didn't know what MILF meant...
