Do you often find yourself in need of the perfect portmanbro -- that is to say, a portmanteau created by combining an existing word with the word bro? If so, I present you with the bronomicon* -- a lexicon containing a selection of perfect bro terms. A lesson in brocution, if you will. Please feel free to add your own brophemisms in the comments.
Bro-down -- A type of bro folk dance, or an event that has many bros in attendance.
Bro-Choice, Bro-Life -- Bros who value the lives and well-being of other bros over literally everything else.
Brocrastination -- Avoiding work by engaging in aggressively bro-like activities, such as cat-calling or shot-gunning a beer.
