Don't use THESE slang terms anymore if you're trying to come off as being "cool."
Quite a few of my coworkers are very happy to hear that two of their most-hated slang terms that are now OVER. But I'm sad because they aren't turnt, stan, bae, ship, bye Felicia, or yaaaaas. We'll outlast those eventually too. Just not today.
The Alan Turing Institute in London analyzed the data trends from Urban Dictionary, and they found strong evidence that two slang terms are not cool anymore and are on the way out: "On fleek" . . . and "selfie."
They also found that the average person has only heard of about one out of every three terms on Urban Dictionary . . . and only about 5% of the stuff on there is also in the actual dictionary.
