dinner with connie
Someone farts in a social setting. This can be heard, smelled, or both. A fine way to draw red cheeks from the offending guest is to casually mention that someone has had dinner with Connie. Connie is a name associated with a person unwilling ever to admit that she ever farts.
A telltale noise goes off between someone's legs at a social gathering. "Well, it seems as someone's had dinner with Connie."
