When your mom over-explains things to you because she forgets that you're a goddamned adult and it's akward.
e.g. mom: "Haha! I brought home this hilarious GOP Bingo card for tonight's debate. See, it's a bingo card, but it has expressions or words the candidates might use. When they say them, you drink a shot! It's so funny! Of course you don't HAVE to drink." you: Yeah, Mom, I knew what you meant when you said bingo. Because I know what bingo is. You don't have to momsplain it."
