Bullschismo

Bullchismo is when someone acts like they are a superior athlete or very masculine, displaying a lot of Machismo. However, in reality they are just average and/or highly athletically uncoordinated, and feel the need to compensate for this by telling extensive and often unbelievable lies about their exploits. This type of individual can be highly annoying as they typically must share how awesome their (entirely made up) exploits are with other people constantly.
