Also some random dude made a good analysis of why it's been popular:
"
In the shitposting sphere there are always certain parameters at which shitposting is exchanged back and forth between opposing parties. As such there are insulting memes and then there are rebuttal memes. Memes develop as a reaction of a reaction. For example porn-posting was dissuaded and laughed at with ironic brap/sniff-posting which was met was unironic fart fetishism and then the magnum opus, the coomer meme. All of which happened months between each other.
But sometimes you have a meme that has no real reaction as to adequately match it. A prime example of that is "Made for BBC". Posters have tried to match it with "Made for BWC" or the more niche "Made for BGC" (Big Greek Cock) whose specificity worked in it's favor. But no response from the humble n word to variations of the phrase was ultimately a match to the tried and true classic. Anytime someone posted a voluptuous woman whose ass cheeks would undeniably need a larger

to penetrate, the BBC posters would ultimately have the first and last laugh.
What rebuttal could be made for something that emasculated this website's core audience? Then, famous shitposter on the other end of the spectrum, Tariq Nasheed, gave to us the perfect opportunity with his film "Buck Breaking". And at an ideal time as the White Boy Summer meme was just recently introduced and in a critical stage of either evolving or fading into obscurity. This Buck Breaking meme emasculated black men due to their historic sexual subjugation at the hands of slave owners. Now normally, there would be a slow burn in shitposting until the Buck Breaking meme matched the BBC meme, but this is a unique circumstance. The BBC meme had pent up too much energy on one end of the shitposting arena so in mere days, years of "Made for BBC" have been overcome by the Buck Breaking meme in a retributive shitpost tsunami. Such events rarely happen and the future of BBC posters is currently unknown."
