4. Heel

Heel, alike babyface, is another term which has become irrefutably linked with professional wrestling, in spite of variations of the term existing before becoming part of pro-wrestling jargon. First coming into public consciousness in the early 19th century, instances of the word heel meaning "a contemptible person" can be found in literature such as Raymond Chandler novels in the 1940s. However, alike shoot, the 21st century has evolved to attribute the term to professional wrestling and its continued usage in popular culture is a credence to wrestling's reach, particularly during the Attitude Era. One particular connection that should also be made is that of the heel turn. TVTropes.org lists the umbrella term of any change in character from good guy to bad guy as the Face-Heel Turn and vice-versa, proving that modern day popular culture has tendrils in professional wrestling.
