שאינו יודע לשאול

1) The dude who has no clue what’s flying and is the 3rd wheel in a group

2) a guy in yeshiva who doesn’t learn, doesn’t make money, and doesn’t chill hard, so basically has no life whatsoever and is completely wasting his time

Moshe: Hey Yaakov, are thinking about going to “x” yeshiva next year?

Yaakov: Nah bro! I heard it’s full of שאינו יודע לשאולs!

Sheh’aino yodea lishol

In Hebrew, you’ll see it as שאינו יודע לשאול.
The origin of this phrase comes from the Jewish Passover Seder, where it discusses how to respond to 4 different types of children regarding the Exodus from Egypt. The wise son, the wicked son, the simple son, and the son who doesn’t even know how to ask a question. That one is known as the שאינו יודע לשאול.

It used to only be used in the context of the Seder, but nowadays it’s generally used to describe anyone who’s a complete dumbass. Someone who has no clue what’s flying. Someone who would be a 3rd wheel in any normal group of people.

Another way the term is used is for a specific type of guy in yeshiva. A guy who doesn’t learn, doesn’t make money, and doesn’t chill hard. If he’s doing one of those 3 things, then he doesn’t fall under the category of being a שאינו יודע לשאול. A שאינו יודע לשאול in yeshiva is the guy who has no life, and is completely wasting his time. For example, it’s the guy who wakes up at 9am, and instead of going to shiur, he’s watching a movie! SMFH 🤦 ♂️

Moshe: Hey Yaakov, are you thinking about going to “x” yeshiva?

Yaakov: Hall nah it’s full of שאינו יודע לשאולs!
