What do straight guys know about Grindr, the gay dating app? According to this video, very little. In other words, they are aware that it is an app and it exists, but that’s about it. One of the guys interviewed thought it was a food ordering app (where, presumably, one could order a grinder). Another thought it was an app for dancing (like grinding, get it?). Watch what happens when the guys dive into Grindr’s world of exposed torsos and way-more-than-suggestive messages.
