Sigma Meal Skibidi Slicers

When someone has a meal at a Gen Alpha restaurant with iPad kids (McDonald's, Wendy's, etc.)

Friend: OMG guys! I just had my Sigma Meal Skibidi Slicers in Mcdonalds!!!

Friend 2: Stop being an iPad kid and have some actual rizz.

Friend: OK, but don't act like a rizzler in front of every sigma. Especially near the Alphas.

Erm, what the sigma

Basically when some insignificant, tiny troglodyte refuses to curse in public and replaces “fuck” with sigma.

“Yo, I’d tap her!”

“Erm, what the sigma,” 🤓

“Literally shut the fuck up.”

Sigma

1. The 20th Old/Ancient Greek letter or the 18th Modern/Classical Greek letter.
2. In mathematics used to indicate the summation of a set or series.
3. In statistics used to indicate something complicated not able to be understood by Urban Dictionary readers.
4. The best meaning: a sigma male. Similar to an alpha male but better. A lone wolf - a self-reliant and assertive male.

1. Yesterday I read a book in Greek and I saw the letter Sigma.
2. Blah blah blah sigma blah blah series blah blah- hey, you, why aren't you listening in class!
3. Mommy, what does sigma in statistics mean?
4. Man, look at this guy, he's such a sigma!
