42nd base by Purlpetupils January 30, 2012
While walking the side street of a largely populated city, an obese transvestite begins to engage in oral sex with his own genitals and asks you to ejaculate into his nostril. Simultaneously, your cousin sees the procedure taking place and summons her bestfriends for a group orgy along with some animals. For best orgasms, it is advised that you have a 5-some with your parents, your cousin, and her bestfriend. It is not uncommon for police officers to shoot a bullet up their anus when they see such things.
Transvestite: DUDE, watch me eat myself out while giving myself a handjob

Police officer: Can I join in and make this 42nd base?

Transvestite: No

Police officer: *shoots self in asshole*

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.
