The novel, on which the TV series airing on Channel 4 and Hulu is based, was written by Candice Carty-Williams.
The book was released in 2019, and a Wikipedia entry about it states that it is about the life and love of Queenie Jenkins, a vibrant, troubled 25-year-old British-Jamaican woman who is not having a very good year.
Arts journalist Andrew Kaggwa Mayiga is among those who appeared shocked that Omutujju's song, which had been criticised as being bubblegum, had attracted such attention.
"Gravity's Okwepicha in an episode of Queenie is yet another proof that art is the most complicated product there is. Who could have imagined Okwepicha ending up in an episode of a British TV series?" wondered Mayiga, who writes for the Daily Monitor, in a post shared on X.
"But again, everyone shouldn't be doing such music; you may not be that lucky."
Commenting on Mayiga's post, Ntare Lucky observed: "Indeed it's luck. As luck would have it, Candice, the author of the novel and creator of the show, has a Ugandan friend that inspired the character Kyazike."
So, as Ntare noted, Okwepicha could have been featured because of the Ugandan inspiration and to make it relatable to Ugandans.
Okwepicha became so big on social media that it inspired an impromptu concert at the Lugogo Cricket Oval in Kampala.
Gravity Omutujju hosted a massive concert in 2022, so fans didn't see another concert coming in 2023.
But because of the song's massive success, Omutujju saw an opportunity to organise another one in 2023 and cash in on the trend.
The song's title is now used as a verb to refer to having sex. It was produced by Bless Touch at Crefila Records.
Its well-received video, which was filmed by Aaronaire, features the comedian Amooti Omubalanguzi.
