Top Definition
A derivation of Occam's Razor applicable in internet comment threads. When interpreting an existing comment, the comment should be liberally interpreted in whatever way leads to the funniest reply comment.
Original Comment: "I want to get the number 2 tattooed on my back so the guy behind me knows what place he's coming in."

Choice of assumptions:
1) the guy behind commenter is coming in place #2 in a race.
2) the guy behind commenter is coming in place #2 on her body.

Fatuity's Razor requires the selection of assumption #2.

Sample Sentence: "Choose your words carefully, because those assholes will apply Fatuity's Razor and turn benign comments into jokes at your expense."
