A lucky chance occurrence, like when this new boy you have a crush on in the 6th grade emails you and asks you to go to a movie and signs off XOXO and you realize just then, he has a crush on you too. That's a kawinkidink!
The supposed way Canadians say 'coincidence'. Similar to koinkidinky but less cute. Similar to koinky-dink but without the unnecessary hyphen. An awful stereotype.
Jacques: We both got stereotyped at the same time for being Canadian, what a koinkidink, Eh?
Brought to public attention by Bob Woodward and Carl Bernstein in the book on the fall of Richard Nixon, All The President’s Men, ratfucker was Nixon’s term for a political operative who sows chaos among opponents; an agent provocateur. It is thought to have originated among campus political rivalries at USC, and seems to have some usage in the US military.
Along with Nixon’s other ratfuckers, Roger Stone caused fights at otherwise peaceful Democratic Party protests to generate a false narrative that the Democrats were violent and dangerous.
