A fork of Rural Dictionary
A variation of the famous Chicago Sunroof, a highly erotic and invasive sex act using the Susan B. Anthony dollars, 3M tape, and a submissive partner. After the completion of the act, medical personnel are usually needed to remove the coins from your anus. Not for beginners.
John is usually never around when the shit goes down, but I was finally able to 3M him and he was shitting change for a week! His screams for one more coin to make 13 in his ass were oddly sad and endearing.
