Originated in Dallas, TX after the millenium, but before that song "I'ma put you to bed" came out.
"I'm about to take a nap"
"I'd like to take a nap"
"This computer is taking forever to boot up. I could probably go get a coffee, bang that secretary in accounting and take a nap by the time it's ready to go."
"You haven't finished yet? Damn, baby! I'm just gonna take a nap already. Wake me up when you're done."
"Hey, waitress, we're just gonna take a nap over here. Wake us up when you finally get around to taking our order."
