It is where men will meet and possibly discuss anything of importance and possibly plan a resolution to the problem. e.g. bloke having missus problems, organising a road trip, pub crawl. These are commonly held friday afternoons either at a pub or a blokes place. Also can be held before sporting events, and anytime where it maybe deemed necessary. And Beer must be consumed.
Bloke texts his mates: Men we need a beer summit at corner pub this fri arvo.
