WATCH: Enraged body builder slaps judge after losing contest

Losing is always tough, but it should never be used as an excuse for aggressive behavior.

A Greek bodybuilder has become an online sensation for all the wrong reasons, as he was videotaped going on a rampage after he lost at the 2016 IFBB Diamond Cup in Athens, Greece.

A totally enraged Giannis Magos was seen jawing at judge Armando Marquez before slapping him in the face.

After the physical altercation, Magos continued stalking around the judges’ corner and flipped off a table. Other witnesses claimed that the hulking athlete even pulled out his penis and exposed himself to the other judges.

“Yesterday I’m winner! Yesterday I winner!” Margos yelled at the crowd, as translated in a New York Post report.

“And today I get beat, how? I don’t understand. (expletive) off!”

Lagos’ frustrations came after he reportedly won his 100-kilogram division but failed to bag the overall title. This was also the third time he had come in second place overall at the annual event, the report said.

The International Federation of Bodybuilding and Fitness (IFBB), meanwhile, announced that  Magos faced a lifetime ban from the sport due to his “disrespectful and aggressive behavior.”  Khristian Ibarrola
