This is a rather obscure expression from someone's childhood invention of their own language. Not only does it rhyme, it also and sounds sort of like when someone mumbles and the sound can remind one of a shoulder shrug.

It's literal translation is "I don't know."

It can also me used as a distraction device when trying to get out of admitting wrongdoing because the two-word phrase itself sounds so bizarre as to throw off your interrogator.

It can be very effective used in a "broken record" or, more modernly, as a "scratched CD" fashion
Mom: Who took all the cookies from the cookie jar?
Tom: Sager Blager.
Mom: What is that supposed to mean, smartypants?
Tom: Sager Blager.
Mom: Can you speak Enlish, PLEASE?!!?
Tom: Sager Blager
(Mom proceeds to violently spank Tom.)

A name that’s commonly given by peasants in the middle eastern realm of the word, literally meaning “hawk” but in most cases usually is given to those with the personality of a pigeon with a severe mental illness.

Sager is the worst kind of person, akin to human excrement, shit, doodoo, the absolute vilest lowliest scum of the earth imaginable. Not only is sager an absolute disgrace of what slightly resembles a human being, he is also a failure to both his parents, his family, his friends, and anyone who comes into contact with him. He has no morals, no ethics, no standards, no professionalism, and no respect as a man. If sager’s parents knew what kind of a disgrace they would be raising, they would’ve ended it and saved themselves the pain long ago.

Sager often likes to think of himself as cool and edgy, this is attributed by him posting dark quotes thinking he’s Batman or something, but in reality, just makes him look extremely immature and honestly, quite stupid.

Don’t be a sager, literally anything is better.

2: “saying you are a bad person would be too much for you, you are so horrible that you receive the worst sentence, you are a sager
