Everyone slips into an alter ego at some point in the night when they drink. It's not intentional, but it happens when you're about 7-8 cold ones deep. I'm not talking about 7-8 Keystone Lights, I'm talking 7-8 Bud-Diesels at the bare minimum.
Anyways, some people go above and beyond when their alter ego rises from below and takes charge. Take this mullet for example. Do you think you'll find someone who has long hair sporting this? The long answer is hell no. This is for the drunk guy who goes above and beyond at the bar getting tanked as all get out with no regard for his safety.
