What sheltered world did this guy come up in? The list of sounds we used in daily life or quotes from entertainment as Gen X was endless. Everything from "Ruh roh Raggie" to the "arr arrr arrr" from Tim Allen's character or various Beavis and Butthead references were never too far away. "Book 'em, Danno" an even older reference comes to mind.
(However, in professional settings this should be avoided. Standard chatter with familiar people in the office you can get away with it)
Dude needs to grow up and remember to be young.
