Open your dick
A term of slang a woman will tell a man who is bad mouthing her. In a moment of fury when you can’t get the proper words out, “open your dick” is a quick alter to “open your mouth.”
“Open your dick again and I’ll hit you”
“I’m from the North End and if you want to open your dick we can fight about it”
