A doujin that will make you lose your mind the more you read it. 177013? 215600? Who are they next to this? NOTHING. The second most fucked up hentai ever, only behind to 228922.

A doujin that will make you lose your mind slowly. Almost impossible to read something more fucked up than this. Only 228922 is beyond this doujin's limits.
Guy 1: Hey bro! I heard 4299 was an awesome fap material.
Guy 2: Kiddo... Stop talking with the person who told you that.

DO. NOT.

This is an actual warning, I'm trying to prevent everyone from seeing the most disturbing, mental, degenerated, inhuman things Japan has ever produced. Whatever deity you worship or whatever philosophy you follow, DO NOT search this number online.
If if you're asking the sauce of something, and someone replies you this, 22345 or 228922, DON'T SEARCH. Never trust any numbers someone sends you as "sauce".
You have been warned.

See: NSFL
Guy 1: May I ask for the sauce?
Guy 2: Sure, 4299.
Guy 1 10 minutes later: *Kills himself*

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.
