Cock Swinging
The act of someone with a big ego bragging about something in front of a group of people. Usually with limited or no merit whatsoever.
EscaVi: Did you see that mass email John sent out CC'ing the entire company staff talking about the number of sales his department cranked out last month?

Daniel: Yeah that was pretty bold. That department ain't shit anyways; There has been a lot of cock swinging going on these days amongst these useless managers lately.
