Hi guys I have a weird question for you I have a girl friend and my best friend (best bud) just send me an app that called grindr and he told me that is a dating app and he also know that I have a girl friend... But he just said to me it is a cool app and it give me a match. but, I love my girl friend more than anything so I didn't want to open it and cheat on her ... And I have just told him ok I will see it. And then I didn't open it to be honest I didn't even installed it. So my question is what the heck is it???? And is it like tinder?
