Were you even here in the beginning?
only gaiafags say faggotry like you. you making it sound as if /b/ liked the desu meme...THEY DIDNT thats why it was so succesful.
it all simply started when dan kim posted he`s "100 percent junk" comic on /a/ and some one had the marvelous idea to spam "desu" just like the comic did. all it did was piss some /b/ tards off in the beginning. so obviously other /b/ tards started spamming it just to piss off other /b/ tards.
desu was a perfect example of a succesful /b/ trolling /b/ type of thing.
hell, a lot of /b/tards didn't even know who the fuck was this "desu" girl that kept getting spammed and ultimately it led to curious people to know the sauce and watch the series (like in my case)
but in then end, it continued to carry on because a lot of those /b/tards eventually watched the series and fell in love with her....like in my case...which is pretty fucking sad but then again this is 4chan.
