Here's a very important piece I unearthed from the Farce the Music vault. It was never posted during the heyday of bro-country, so it has lost a little relevance, but there are still bros out there and you should at least attempt to understand their language.
This is a handy guide to deciphering bro-country fans' slang and acronyms on social media and text messages.
