What is your psychology when you boys talk about a girl sending her own photos? curious ...

The first possibility, which is really destructive, is to think about whether two people have a holiday (probably a deep hatred? )。

Second, it's fake. It's possible that boys have a crush on girls. I believe that some boys with low emotional intelligence expect to get her attention by bullying girls … to make her like herself?

The third party, just joking, may not grasp the scale or say something that he doesn't care about but makes you feel big.
