That's a rhetorical question, by the way—I know exactly what egg-nog is.
Nog is one of those stupid made-up words you only ever get to hear at Christmas, like swaddling, manger, figgy and myrrh.
Someone is definitely taking the piss.
What in God's holy name is egg-nog?
.....and virgin, of course!
No, it's not a silly made-up word. Meaninga bottle of old strong beer, it's been around since 1691. As egg-nog it's been used (mostly in the States) since 1891.
It's also meant a peg of wood, etc., since 1571.
Isn't that boring?.
Extremely.
But it's still not a proper word.
I tell you "nog" is the most important word in the world - you should be ashamed that you don't use it more often.
Sorry - just playing Devil's Advocaat.
