Man 1: Josh Allen said the n-word on twitter back in 2012 when he a junior in high school! What a totally racist asshole!

Man 2: Dude, EVERYONE has said stupid shit at some point in their life, ESPECIALLY high schoolers! I'm not going to chastise someone for something obviously nonsensical they said as a dumb kid, where the only difference is that he was unfortunate enough to say it in a place that saves everything as opposed to normal face to face conversation. Especially when it's totally a coincidence it only came out after he became famous. Quit birching and get a real fucking hobby.

birching 

An application of birch twigs to the bare posterior of a miscreant of misbehaving person. The goal of this is to provide an attitude correction. In past years the process was used by husbands to correct their wives, giving rise to old English "rule of thumb" that is you were not legally allowed to birch your wife with a stick that is larger in diameter than your thumb. Sort of counter productive anyway because the best birch branches to use are about 1/4" in diameter and freshly cut so as to be flexible and whippy. The process of birching often requires the woman to prepare her own birch.

In the case of submissive women receiving a birching often gives rise to strong sexual desires and a feeling of contentment and calm.

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.
