Germán Genaro Cipriano Teodoro Gómez Valdés y Castillo, known professionally as Tin-Tan, was a Mexican actor, singer and comedian who was born in Mexico City but was raised and began his career in Ciudad Juarez, Chihuahua. He often displayed the pachuco dress and employed pachuco slang in many of his movies, some with his brothers Manuel "El Loco" Valdés and Ramón Valdés. He made the language of the border Mexican, known in Spanish as fronterizos pachucos, famous in Mexico. A "caló" based in Spanglish, it was a mixture of Spanish and English in speech based on that of Mexicans on the Mexican side of the border, specifically Ciudad Juarez.

Ciudad Juárez, commonly referred to as just Juárez, is the most populous city in the Mexican state of Chihuahua. It was known until 1888 as El Paso del Norte. It is the seat of the Juárez Municipality with an estimated population of 2.5 million people. Juárez lies on the Rio Grande river, south of El Paso, Texas, United States. Together with the surrounding areas, the cities form El Paso–Juárez, the second largest binational metropolitan area on the Mexico–U.S. border, with a combined population of over 3.4 million people.
