Well, I'll tell you the strangest thing I seen on grindr. This was about a year ago or so.
I was in an area of LA I'm not usually in and I pulled up grindr for shits and giggles, and I see my old junior high school principal. lol.
I always assumed he was, or at least open minded. Most school staff are kinda homophobic.
In the sixth grade, I once beat the shit out of this bully real bad who called me a faggot.
I was sent to the principal, and I never got punished or in trouble, and my parents were never called. He said if he tried to bully me again, that he would call the police. In fact he actually let me eat lunch in his office. He was real nice.
I never messaged him because I was too scared too, because then I could have saved my in my buddy list or something. Again since I was in a area I'm not usually in, I never ran across his profile ever again. But it was nice to see I was right and he was gay.
But yeah, I constantly get guys who straight up ask what they want and do what they want. they immediately send dick pics, which might not even be theirs, or ask if your a top or bottom, by "TP" or BTM". So rude.
