I'm sure I have run into IC-yet-cringey vocabulary, but aside from the notorious "weeping cock" I can't think of any - not from fanfic, anyway. I suspect my occasional dive into Nifty and Literotica have recalibrated my Awful Sex Words Detector to be a bit more lenient, given the kinds of egregious OTT vocabulary that's popular there!
