Synonym Toast Crunch 

When one uses other words, on purpose to exaggerate or by accident because they don’t know how to spell, to build another word.

To exaggerate:

Person 1: How was your history class today?

Person 2: Not so great, I had my final eggs ham.

Person 1: Hmm, using synonym toast crunch? I guess it didn’t go to well at all?

Just plain stupid:

Waiter: *brings food to customers*

Customers: Thank you!

Waiter: You’re welcome, enjoy the meal and bone-apple-tea!

Customers: *to themselves* What a bad case of synonym toast crunch. I think she meant bone apetit.
