Gonnegtion is term used in the novel The Great Gatsby. Meyer Wolfsheim mistakenly takes Nick for a criminal and asks if he is looking for a gonnegtion. The word is a misspelling of the word "connection" in order to emphasize Mr. Wolfsheim's pronunciation. Many people have been thrown by the word, and have scrambled to dictionaries in hopes of getting a definition.
"I understand you are looking for a business gonnegtion"
