A YouGov poll found that whether it’s Millennials, Gen X-ers or Baby Boomers, when asked which “slang” words they would use to describe something positive or favorable, three words come up most often: awesome, cool, and nice. 18- to 24-year-olds use “awesome,” “cool,” and “nice,” most often too, but they’ll also go with “lit,” (23%) “sick” (16%) or “fire” (12%.)
