"Pass Out" is the debut single by British rapper Tinie Tempah. It is the lead single from his debut studio album Disc-Overy (2010) and his debut single on Parlophone. The song was a digital-only release and was available to download in the United Kingdom on 17 November 2009. Producer and writer Labrinth provides vocals on the song's hook, but is uncredited. A remix featuring Snoop Dogg was released in the United States on 16 November 2010 for digital download. In 2011, Labrinth revealed that Tinie would be releasing "Pass Out" in the US. It was re-serviced to radio stations in the United States as the third single from Disc-Overy in October 2011.
After signing to Parlophone, Tinie Tempah was put together with producer Labrinth and the collaboration resulted in the first two singles for the label, "Frisky" and "Pass Out". Parlophone president Miles Leonard said the label was adamant that "Pass Out" would be the first single, saying: "It set new precedents for British urban music from what had been happening the year before. And it was a new sound; it sounded fresh, and like it came from the clubs. Both "Pass Out" & "Frisky" were mixed by London's up and coming mix engineer Mr Jones @ Detox Audio." However, the label thought the song may have had too much of "an edge" for daytime mainstream radio to take a risk in playing it, and so planned it as a low-key "set up single" that was instead made available to specialist radio stations. The song ended up getting such an enthusiastic reaction from specialist radio audiences that it was crossed over onto daytime mainstream rotation. Tempah explained to The Sun that the song is about "getting so out of it that you pass out". The song also mentions Heidi Montag and Audrina Patridge of The Hills, fame and action star Jean-Claude Van Damme and Prince Charles.
"Pass Out" entered at number one on the UK Singles Chart and UK R&B Chart, selling just over 92,000 copies. The single held on to the top spot for two consecutive weeks before falling to number two in favour of Lady Gaga and Beyoncé's single "Telephone". The single spent a total of seven weeks within the top ten before falling to number thirteen. As of 13 June 2010, the single had spent a total of 15 weeks within the top forty of the UK Singles Chart. Then the song re-entered the Top forty at number thirty at the start of 2011, showing the song's popularity, 44 weeks after release. It then re-entered again at number 32 a few weeks later, due to his performance at the BRIT awards. It spent a total of 65 weeks on the UK Singles Chart, making it the joint twelfth longest runner of all time.
In the Republic of Ireland, "Pass Out" debuted number thirteen on the Irish Singles Chart. In its fourth week on the chart, the single climbed to its peak position of number six, where it remained for two consecutive weeks. The single spent a total of four weeks in the top 10 and, as of 3 June 2010, a total of thirty weeks within the top fifty. In New Zealand, "Pass Out" debuted in the New Zealand Singles Chart on 10 May 2010 at number 40. The following week, it climbed seven places to number 33, where it remained for two consecutive weeks.
The music video is focused around Tinie rapping and Labrinth, who sings the chorus, coming into the shot. Other British rappers, including JME from Boy Better Know and G Frsh, also make cameo appearances. The video on Parlophone's official YouTube channel has had over 55 million views since its upload on 23 December 2009. Tim Bown, the director of the video, said in the behind-the-scenes video that they were trying to create graphical elements, including laser-cut props.
