Sanchez, no primary sources exist that support this claim and is an urban legend. The earliest documented usage of puto being chanted by fans in this manner occurred on 22 May 2004, during the second leg of the Clausura 2004 repechage match between Cruz Azul and C.F. Pachuca. Fans of Pachuca repeatedly chanted puto every time Óscar Pérez performed a goal kick. Sanctions Due to the homophobic meaning of the word puto in Mexican Spanish (a vulgar term for a male prostitute), the chant received negative attention in the 2014 FIFA World Cup. Mexico's fans defended it as being traditionally used in the Liga MX. On 23 June 2014, FIFA dropped an investigation, concluding that the chant "was not considered insulting in the specific context". Football Against Racism in Europe, an anti-discrimination organization, criticized the ruling as "disappointing". In 2017, in advance of the 2018 World Cup, FIFA fined the Mexico football federation over fans' use of the chant and introduced escalating sanctions, which were first applied in Liga MX games in 2019. In 2021, three Mexico international matches in the United States were halted because of fan behaviour, including the CONCACAF Nations League final, in which fans also threw things onto the pitch and Giovanni Reyna was hit in the face by a heavy object. On 18 June 2021, FIFA announced that as a penalty for the use of the chant in a pre-Olympics tournament in Guadalajara, spectators would be barred from Mexico's first two qualifying matches for the 2022 World Cup. Rivalries United States Mexico and the United States are widely considered as the two top teams in CONCACAF. Matches between the two nations often attracts media attention, public interest and discourse in both countries. Although the first match was played in 1934, their rivalry was not considered major until the late 1990s, when the USA emerged as a solid international side. On 15 August 2012, the United States defeated Mexico at Estadio Azteca in the first victory for the U.S. against Mexico on Mexican soil in 75 years. Since their first meeting in 1934, the two teams have met 73 times, with Mexico leading the overall series 36–22–15 (W–L–D), outscoring the U.S. 144–82. Mexico dominated in early years, with a 22-2-2 record through 1980. However, since that time the series has become much more competitive, largely due to the rapid growth of soccer in the United States.
