Sick Sick Sick Jokes
from Fancyclopedia 2 ca. 1959
A fannish fad, like boptalk, cuddlypets, and so on. They are anecdotes, gaglines, etc, which supposedly make the auditor shudder in revulsion, on getting the point; assuming that he is tenderer-hearted than a ghoul, or has taste in jokes. And some use the phrase simply to mean off-beat humor, tho it is incorrect to do so. Often the SSS is pure dialogue without any stage-setting, like: "Hell, Aesop, if you've got something to say, say it", or "Gee, Mary, don't those three criminals up there look silly?"
