For those who weren't around when Chatroullette came about -- it was (is) a site that matched random webcam users up for anonymous connections, where you would randomly meet people from across the globe. It quickly turned into a random online exhibitionism tool.

In 2010, Chatroulette was the “it” site. It was profiled religiously, as was its eventual rise and decline in popularity. By June of that year, reporters had gone from singing its praise as “the future of the internet” to writing its obituary (“Cause of death: penises”)... The men who remain — and make no mistake, they are overwhelmingly men — still consider it a place to waste a little time online... Between the occasional, curious user who is truly interested in just chatting, are the ones everyone has come to expect: the on-cam men jerking off.
