The original meaning was more "extraordinary" because the origin of "doozy" was a luxury car in the 1920s called a Duesenberg. People would see the car coming down the street and say "That's a doozy!" However, today it is used for either extraordinary or bizarre.
ho trovato questa parola (in un manuale tecnico) nella frase:
"it's inevitable that the Number data type has at least one quirk, and this one's doozy: 0.1 plus 0.2 will not equal to 0.3"
1. doozy something that is difficult or daunting man that history exam was a doozy! i think i failed
2. doozy Something extraordinary or bizarre. Etymology: perhaps alteration of daisy, and Duesenberg, a luxury car of the late 1920s and 1930s. It's an English expression. "That footballer's form is a doozy!",
"Man, that one was a real doozy!"
3. Doozy Puts emphasis and significance on a certain thing, can be used in almost an circumstance for anything. wow what a goal, that was a doozy
that was a doozy of a meal Mrs. Smith
that girl has a doozy of a rack
I imagine that in your context that it means "bizarre".
