Donkay means many things. Originally it was an expression of excitement, as in, you are in an airport on your way to a
hedonistic Hawaiian vacation and you exclaim, "Donkay!!"
Oddly, it
morphed into meaning, "penis" and then started being used to describe the sex act, even the vagina. It morphed again as a term of endearment, "Hey
donkay girl"- it can even be used as a salutation, as in "donkay" (initial text to someone)- that person might respond with, "Donkay!" or something entirely different like, "what are you up to?"
Again, "Donkay" means many things.
Example:
"I hope your new BF has a big
donkay!"
"Did you let him get to third base and touch your donkay?"
"It's certainly not very lady-like to get
donkay'd on your first date!
"
Donkay girl! long time
no talk to!"
