Con Ed

(US, informal) Any unwanted product or commercial failure, especially one given much publicity.

(pejorative, UK) Of or pertaining to the Conservative/Liberal Democrat government.

A casual slang shortening of 'condom' — the kind of informal word used when you want to be matter-of-fact about contraception without using the clinical term or making it awkward. It's breezy and practical, the sort of word that comes up in a pharmacy conversation or a frank talk between friends. Not especially widespread, but perfectly functional and widely understood in context.

(Canada, informal) A member of the Loyal Edmonton Regiment.
