Male-bonding ritual
Any activity that brings two or more males together in an emotional, spiritual way, causing them, even if only for a spec of time, to tap into their universal masculine awareness of each other. One of the few times it is not considered gay for males to hug one another. Apparently, women walk around in this perpetual state of understanding "all things feminine" at all times, while men have to be jolted into this subconscious state.
War, of course, is the only TRUE male-bonding ritual, with hunting and jointly pissing on Cooper Minis a close second and third. While sports and dancing around thumping on a drum can do in a pinch, only death and destruction can properly bond true males.
A true male, even a male-bonded male, will never utter the words Male-bonding ritual, unless in a disgusted, totally repulsed manner.
