Whether we like it or not, America is a culture that loves celebrities. And where there are celebrities, there are enormous egos who often start epic feuds.

From the 1940’s until the 1960’s a legendary feud reigned between screen queens Bette Davis and Joan Crawford. In the 1990’s rockers Axl Rose and Kurt Cobain had it out for each other. Most recently pampered pop princesses Katy Perry and Taylor Swift have carried on their own passive-aggressive cat fight.

But now a feud has emerged between two antagonistic bros that actually could result in fisticuffs. You know, mano a mano type stuff.

There’s really bad blood right now between Medal of Honor recipient Dakota Meyer and Instagram celebrity Dan Bilzerian.

We all know about Meyer and his courage. However, if you don’t know who Bilzerian is — and I didn’t, until this weekend — well, let’s just say he’s less honorable than Dakota Meyer. A lot less. He grew up wealthy, and has lived off a trust fund from his father, a corporate raider and white-collar criminal. Bilzerian tried but failed to become a Navy SEAL. However, this “King of Instagram” shamelessly promotes himself as a gun-toting tough guy who is irresistible to women. Bilzerian even once bragged that his “greatest fear” was that “someone will break in and I won’t be able to decide which gun to shoot them with.”
