"Sexiest" is the superlative adjective of "Sexy". The fact that you're up on a soapbox whining about the meme, and you keep referring to it as "most sexy", not just once but several times in rapid succession, is almost funnier than the mean itself.
I suspect that what your Tide Pod addled brain means to say, is "Sexist". Totally different word, totally different meaning.
Spelling is part of your grade.
