English is a living language, which means it’s continually growing and adapting to reflect vernacular usage.
Even words that don’t exist in English (officially) can find their way into casual conversation.
It doesn’t really matter if we insist they’re “not real words.”
What makes a word real, anyway, if not the fact that real people are using them?
Fake words have a way of catching on.
And sometimes, there’s a good reason for that.
