To Reggaeton fans he is commonly known by the nickname "El Abayarde" which refers to an insect commonly found in Puerto Rico similar to a fire ant.The name is of course is a reference to being bothersome and behaving improperly as a child.

His lyrics speak of the struggles of the Puerto Rican people, involve topics of racism, inequalities, and ghettos in Puerto Rico, and have strong nationalist undertones.   Wikipedia
