I'm going to write this just so our conservative friends can't say I brush these things under the rug.
There is still a culture of shame around discussing this stuff—and it makes it so, so easy to brush it under the rug.
The New York Ivy has become the latest in a string of schools to be accused of sweeping charges of sexual assault under the rug.
1550s, "coarse fabric," of Scandinavian origin, cf. Norwegian dialectal rugga "coarse coverlet," from Old Norse rogg "shaggy tuft," from Proto-Germanic *rawwa-, perhaps related to rag (n.) and rough (adj.). Sense evolved to "coverlet, wrap" (1590s), then "mat for the floor" (1808). Meaning "toupee" is theater slang from 1940. Cut a rug "dance" is slang first attested 1942. To sweep (something) under the rug in the figurative sense is from 1954.
