Charlie Zelenoff is a Russian-American YouTube personality who was born 1989 in Los Angeles, California. He has a passion for boxing and goes by the nickname "Z-Money" in his satirical boxing career. His videos have turned his YouTube channel into a massive success even though he loses most of his fights. Zelenoff firmly believes he is the best boxer in the world but the boxing community largely ignores him altogether. Occasionally he gets sparring bouts with professional boxers where he often gets beaten up and uploads the videos to YouTube. Zelenoff even claims to be the "UBF World Champion" and carries a title belt. He also tours gyms where he fights amateur boxers and allegedly knocks them out with his "4,500 PSI" power shots. Zelenoff's most famous exchange was between boxing legend Floyd Mayweather Sr. The video garnered over 4 million views since it was uploaded on March 23, 2017.
Thousands of commenters say they enjoyed the video while others critique it. Zelenoff is basically just jumping around the ring the entire time trying to keep from getting knocked out by the older Mayweather. The video is still featured on Zelenoff's YouTube channel and he still carries on his charade as the so-called best boxer alive which is founded in satire more than any actual evidence.
