This reminds me a lot of when you're in a crowded bar and have to nudge someone in order to get to the area you need to get to. Sometimes drunk homies get all offended and make a thing of it, given that they think this is the year 300 BC, and punching a random dude in the face will make every single girl in the entire place want to have sex with them. These are among the worst people out there, mostly because they fail to recognize that they command zero importance in the situation--all in all, there is never anything more to these things than being a person who got his shoulders brushed up against another in a crowded space. No one cares that you sometimes go to the gym. 

This escalates sorta like that. It's almost a bit tough to watch.
