Not a blowjob. Not at all. It's like a French kiss, but "down under." The entire point of the word is that it's a euphemism for cunnilingus, not fellatio.
Did you see that they used "Australian kiss" as a word during the "Cunning Linguistics" game on On The Spot?
No I didn't. I DID, however, see that they used "an Australian kiss." It sucks that some idiot submitted THE WRONG DEFINITION under a slightly different name, seeing as how the name of the game is a pun on the word "cunnilingus."
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.
