Urban Dictionary "on fleek" definition

I know it's urban dictionary and they're a humor site sometimes but people need to chill with the hating on slang and thinking they're Superior for not using it

ROASTED

Here we see the definition of "I don't understand the fluidity of language or the concept of casual words versus formal. I have no friends and don't realize it's because I'm a pretentious asshole."

That moment when your definition is on fleek

Language should be fluid, certainly; however, it should not devolve into pure nonsense. Instead, it should incorporate new words and nuances to keep in pace with other exponentially expanding fields (e.g. sciences and technologies). In particular, English already has too many synonyms, so we don't need to arbitrarily add more and turn the language into a hodgepodge jumblefuck.
