Definition: The slang or profane phrase you're referring to is "Luke 17:23," which means "A man who believes in a God and doesn't worship him." This term has been used humorously as the catchphrase for a prank, where someone would tell their friends that they were not bowing down to Luke's father.

Here’s an example sentence using this slang phrase: "I just saw a crazy person go around with his hand outstretched. They looked like they were holding something and they said 'Luke 17:23, I am not going to bow to you.'" This sentence is considered edgy because it suggests a man who holds the belief that he is above God is willing to do just about anything for others' respect or obedience, much as Luke did. It's meant to be humorous and adds an unexpected twist to a common proverbs reference.
