French hip hop stands out for its "flowing, expressive tones of the language give it a clear identity within the rap world." In many French rap songs, verlan is used which is a slang that twists words by reversing and recombining them. This makes it difficult for even French speaking listeners to understand what the MC is saying. Even though it is difficult at times to understand completely the lyrics that are being said rappers still get the heat for causing violence and disturbance within society because of their intense message of rebelling against the system.
