This video, called 'Man Smacks,' focuses on that very thin line between an awkward hug and a comfortable hug between two bros.
The appropriate hug is a "man smack," hence the title of the video. The dedicated etiquette coach put together a set of examples from various films and television shows to drive the point home. There are perfect examples of the Sopranos men and the Entourage boys all performing the proper bromance hug.
The infamous Hangover hug is also in this video--but as a perfect example of what not to do.
