#1 Wooo!
Ric Flair is one of the greatest wrestlers ever and his work on the microphone is just second to The Rock’s and on-par with Chris Jericho and Paul Heyman. Flair has a lot of catchphrases during his career like “To be the Man, you gotta beat the Man” and “The Stylin', profilin', limousine riding, jet flying, kiss-stealing, wheelin' n' dealin' son of a gun” but the one that stood out the most is “Wooo!”.
The catchphrase was simple and borrowed by Flair from the song “Great Balls of Fire.” Flair even made it bigger than the song itself with “Wooo!” crossing over the sports and entertainment industries way before the “What?” and “YES!” chants.
Fans still chant “Wooo!” for every knife-edged chop in any wrestling match in the world. It has also been used by many athletes, sports teams, celebrities, rappers, and in pop culture in general over the past 30 years. The “Wooo!” chant being this popular makes it the greatest one-word catchphrase of all-time.
