Every year a new trend hits the streets (quite literally in some cases). Whether it's a bunch of Santas and elves sucking down Christmas cheer by the pint, comic book heroes and villains cosplaying themselves into an orgy-anic frenzy, friendly zombies, or simply bikes with neon lights and boomboxes, one factor always remains the same: the participants in these “crawls” are grown-ass adults — and drunk.

Like clockwork, revelers in Denver, Colorado, took to the streets last weekend at the Great Onesie Bar Crawl, crisscrossing the streets without warning and generally disregarding the rules of society like the rebels they are. This is bar crawling, and it’s going nowhere soon.
