#12: Dealio
Most of us use the word “dealio” in a half-joking way. We usually use this outdated slang word as a way to annoy our kids or grandkids. How could we possibly be so out of touch and uncool? Don’t worry, we were cool once. As we age, we’re okay with our lack of cutting-edge slang. That’s why using the word “dealio” is a-okay with us.

“Dealio” might sound super unhip, but it probably arose from a completely normal phrase that people still use today. The general consensus is that “what’s the dealio?” came from people mishearing “what’s the deal, yo?” It also could have been created when people said, “What’s the deal, yo?” really fast. Aren’t slang words super neat?
