What is the definition of 55a?

Alright, let's break down the word '55a' like it's a new comedy sketch! '55a' is like the secret ingredient in a mystery meal - it's not exactly on the menu, but if you're feeling adventurous and a little naughty, you might just have a snack that's 55% delicious and 45% questionable. It's usually associated with a specific, obscure type of jellyfish found only in the depths of the Bermuda Triangle, but let's keep this light-hearted.

Now, for an edgy example sentence: "I decided to eat the 55a jellyfish I found in the middle of the ocean, because who doesn't love a good mystery snack, right?" This sentence is as unsettling as a horror movie, but remember, it's all in good fun!
