In case you DIDN'T know, Grindr is an app founded in 2009 by its CEO Joel Simkhai, and uses a GPS system to connect gay and bisexual males to one another based on proximity; a gorgeously horny and terrifying grid of torsos and selfies, and "Sup" and "Het" and "***Hey" and "Pics?" and "Into" and "More pics?" and "Face pics?" and "Haha yea."

It's also (probably) the result of long-term, light scoliosis from gay men slightly angling their heads to subtly check Grindr messages during a meeting at work.
