Something (a place, person, plan, or season of life) that is cute, quaint, or endearing yet ultimately a dead end.
"That whole season of my life was wimble"
"She had eyes for Jason but his heart knew she was a wimble to him"
"He knew the café job was a wimble, but he liked the smell of roasted beans in the morning"
A Dirty Wimble is when the small end of a traffic cone is inserted fully into the participants anus, then (usually with the assistance of a laxative) the second participant will place themself at the large opening of the traffic cone while the other releases there bowels in an explosive and spectacular manner.
