The language of idiots. Every pair of best friends has their own divergent dialect, and other people can only learn it by hanging out with you and your friends for long periods of time. Idiotish is a common language, but is most commonly spoke by the following:
-Teachers who assign homework on weekends

- Donald Trump

- Your ex
- Every music artist ever. (That's why it's so hard to understand music lyrics)
Note: The only language that your siblings speak is idiotish. It is always polite to dumb down your speech so that they understand.
We were supposed to write an essay on trees this weekend, but I didn't know because all I heard was the English teacher spewing idiotish.
