Guy friend exaggerates how much money he makes infront of me? Why do men do this?

I don’t get why he felt the need to do this! It almost seemed like he was “peacocking” even though I’m very obviously just a friend to him. He asked me how much money I make and then he said “oh yeah I make that each day easily!” (Which isn’t true) I wasn’t trying to one-up him or show off, I just gave him the true figures because he asked me, then he started exaggerating how much he makes, which seems very odd.

It’s just a bit strange that he’s trying to impress me when other signals he gives off show that he’s not interested in me in that way!
