My father taught us how to play when we were kids. It was popular in his neighborhood (in upstate NY).
Anyway, he told us this story of a rather thick-headed fellow who simply could not accept the idea that sometimes, when another player was a point away from winning, you did not want to euchre someone, i.e. you’d have to let them win some tricks. Because if he got euchred, all the other players would get the points and the highest guy would then win the whole game!
Well, this guy did this so often they wound up creating a catch-phrase anytime somebody wanted to do something obviously stupid:
"You’re Euchred! Here’s my dollar…"
We still say it today!
