A thumbs-up brofist is the act of brofisting your brosef, possibly while drinking brooskis, while making a thumbs-up with your hand, and turning it sideways in a fluent motion.
"I was talking with my brosef over some beers, and when he chugged that brooski, a brofist wasn't enough. I made a thumbs-up, gave the signal, turned it sideways, and thumbs-up brofisted him.
