What is satire? is it like the phrase "ur mom"?

Satire is sarcasm or the use of humor, irony, exaggeration, or ridicule to expose and criticize people's stupidity or vices.

A lot of times it's used for politics to mock the politicians involved in the campaigns.

to me i think class room sitting education is better. i do online school and i have not learned a think haha. when i sit in the classroom i just sit there and kind of pay attention but still i get so far ahead in the class when im doing online i have nothing else better to do but play video games and i sit in school and learn and have friends and just actually learn. when i'm doing online i sit here listing to music and get on and and look up the answers i guess that is my fault for being a cheater. but to be honest i think sitting in the classroom is better.
