At the 2015 BRIT Awards, Kanye West called upon Skepta to invite "30 goons" onstage during his performance of "All Day".
Skepta chose to invite a collective of grime MCs and British rappers to represent their music scene, and among these was Stormzy.
Fellow artists Big Narstie and J Spades downplayed this achievement, calling Stormzy a "backup dancer" during the performance.
The line "Mention my name in your tweets / Oi rudeboy, shut up" is widely believed to be addressing Cadell, an East London MC and the younger half-brother of Wiley.
"Shut Up", as well as Stormzy's other songs "Standard", "Hear Dis" and "Scary", are regarded as being diss tracks in response to Cadell.
On 12 December 2015, Stormzy performed "Shut Up" during British heavyweight boxer Anthony Joshua's ring-walk for his fight versus Dillian Whyte.
