Bitches Don T Know
Bitches Don't Know is a 2006 exploitable image macro built from a Myspace photo of Rich Owens in a shirt reading 'BITCHES DONT KNOW BOUT MY DICK.' 4chan users swapped his face onto other characters and rewrote the shirt with niche brag lines, spreading the template widely through the late 2000s.
Overview
Bitches Don't Know is an exploitable image macro built around a Myspace photo of a man in a plain t-shirt printed with 'BITCHES DONT KNOW BOUT MY DICK'1. The exploitable version swaps the man's face for another character and rewrites the shirt so it reads 'BITCHES DONT KNOW BOUT MY [X],' filled in with whatever niche skill or interest the pictured subject supposedly owns3.
The catchphrase itself also works as a standalone reply, used to affirm something impressive that outsiders would fail to get2. The template's flat-faced pose keeps the boast on the shirt looking dead serious no matter how ridiculous the substitution is1.

How to Use This Meme
Making a Bitches Don't Know edit usually starts with the original body pose from the Owens photo, then Photoshopping a new face on top and rewriting the last word of the shirt line to something the pictured character would plausibly brag about1. The blank at the end is typically a niche skill, obscure hobby, or in-joke tied to the subject. Keeping the block-letter shirt font and the deadpan expression is the usual convention.
