The day after Thanksgiving is usually a snoozer at Stranger HQ—except for those who care about shopping and/or are expected to leverage the absurdity of Black Friday into some pithy observation about the economy. If you're anybody else, please enjoy this video of a football player who may or may not have purposefully kicked another football player in the groin.
Which brings us to the day's etymology: groin.
1590s, earlier grine (1530s), from M.E. grynde "groin" (c.1400), originally "depression in the ground," from O.E. grynde "abyss," perhaps also "depression, hollow," from P.Gmc. *grundus.
I'm going to start using "grundus" instead of "groin." It sounds better, more earthy and visceral. The OED says "groin" comes from "depression" because the grundus is in the "fold or depression" between the abdomen and the thigh.
And here's a little groin-related medical advice from Lanfranc's Science of Cirurgie, circa 1400: "If þe prickynge be in þe foot, anoynte þe grynde wiþ hoot comoun oile." I think that means that if your foot hurts, rob hot oil on your grundus.
