A method of getting intoxicated that shows your bravado by doing a bong hit without exhaling then immediatly followed by a beer bong, upon which the person exhales. Similar in purpose to a strike out. Adding a shot of whiskey after doing the beer bong is optional but not for beginners.
Tom and Mike have been on a 12 hour acid trip and want to go to sleep but are still tripping. They decide to do a bong bong so they can sleep. Tom holds a filled beer bong while Mike takes a full hit off of a bong. Mike holds the smoke inside of his lungs and then drinks the beer bong and then exhales. Tom and Mike reverse positions so Tom can do his bong bong. They repeat this process until they pass out.
