Hi. I am looking for a word or an idiom describing a situation in which someone does sth to frighten others or to make an impression so no one else dares to do similar thing.

For instance when students are noisy, the teacher kicks one of the students out so other students do not dare to make any noise.

The context can be as follows:

Ex. Our teacher just kicked me out as/to/for . . . . . . . . .

I hope I was able to convey what I mean.

I greatly appreciate if you would tell any words or idioms that come to your mind.

Thanks

The teacher kicked me out of class to make an example of me.
a Chinese saying would be 'killing the chicken to warn the monkeys'
Students: Are you brave enough to let our tutors analyse your pronunciation?
Thanks Khoff, but I need something stronger than make an example.

Thanks
Thanks, that was a nice one.

I am looking for such a thing in English.

In Persian we say the teacher kicked me out of the class to get the venom of eye.

I wonder if we have similar idioms or words in English.
beat the dog before the lion ?
Students: We have free audio pronunciation exercises.
Hi

You ask:

I am looking for a word or an idiom describing a situation in which someone does sth to frighten others or to make an impression so no one else dares to do similar thing.

In a London-based gangster film, it is known as "The famous Archie slap"

It is more humourous than violent, but I must leave you to google the reference, if you wish

Best regards, Dave
thank you very much
