While reading these comics, I came to one solid conclusion.
Apparently in some daialects of english "Gay" "Homo" and "Butt/Ass" must always occur in that order, and always together redundant as it may be. "Sex" may attatched to this previous combination of words to connotate anal intercourse. Apparently using the word combination "Gay Homo Butt" or "Gay Homo Butt Sex" enough is hilarious in the sub culture that speaks this daialect.
I fail to see the funny here though.
