Lingo like "LOL" and verbs like "TO GOOGLE" didn't exist but check out the ones that did!
Another interesting 80’s phrase with a deep past. The word “duh” had been used to express bewilderment or ignorance since the 70’s, but adding “no” to the front created a sarcastic expression that points out the obvious. Replying ‘no duh’ to a statement made my another showed that you were way ahead of them when it came to putting things together.
“Sheena Easton is wicked hot.”
“No duh, man.”
"WHAT'S YOUR DAMAGE"
Simply put, it’s the phrase “what’s your problem?” stuffed into a time machine and sent back to the era when Heathers ruled the box office. It can also be used to imply that someone else is an idiot for having a specific opinion, or for doing a certain thing: “You like Wham! but not Tony Basil? What’s your damage?”
