The urban dictionary is useful because there are some cultures that use words or phrases you won't particularly see on a day to day basis.
For instance, I'm 100% sure you don't know what the word "beuy" means. That's a term that is consistently and constantly used where I'm from.
I spell it bey, but that can be confusing for people that know what the official definition and spell of "bey" (pronounced bae) is.
Some spellings for the word I'm talking about include "bey/beuy/buy/bui", mostly because there is no correct spelling for it since it is simply not a real word. It's a very, and I mean very, universal word where I'm from, lol.
