• To be too big for one's boots is to be conceited, arrogant, and have too much self-importance. Stormzy is warning someone here that if start behaving as if they are more important than they really are, he won't hesitate to boot them back down to size with his size 12s.
• The song was co-produced by grime DJ Sir Spyro and Fraser T. Smith, who is best known for his work on Adele's hit single "Set Fire to the Rain". It was BBC 1Xtra DJ Twin B who introduced Stormzy to Smith.
• Stormzy spoke to Beats 1's Julie Adenuga about Smith's contribution, which included the high-pitched vocal sample. "He's] someone who's so skilled and at that upper echelon of the game… I was just looking forward to seeing what happens. Spyro had laid such a sick foundation that the drums were mad and there were chords and they were mad… I had an idea to get a sample in there 'cause I feel like samples are so grime… to get that flippin' old school crud."
• Stormzy told Julie Adenuga the story of the song. "I invited Spyro into the studio he's the top boy. he's so shy he'll have a riddim and then he'll be like 'Oh I'm not sure you're gonna like it.' He sent me that tune and then me and Fraser took it and Spyro had laid such a sick foundation the drums and chords were mad and I had an idea to have a sample in there, and then just the feeling of the way that tune was constructed, that was like me being very creative and adding up to what I already do."
• Gang Signs & Prayer debuted at #1 on the UK album chart with combined chart sales of 69,000. It is arguably the first pure Grime album to reach the summit of the tally. (Tinie Tempah's Disc-Overy is the only other Grime-influenced record to reach the coveted top spot.)
• Gang Signs & Prayers beat the record for the most first-week streams of an album in UK chart history, surpassing the opening week of such streaming giants as Drake and Justin Bieber.
• The Labour MP for Stormzy's hometown Croydon Central, Sarah Jones, referenced a line from this song during her maiden House of Commons speech on July 12, 2017. Commenting on the lessons to be learned from the general election held the previous month, she said:
  
  "If the election has taught us anything, it's that we cannot take anyone for granted. As Croydon's Stormzy put it so well in one of his songs: 'You're never too big for the boot'".
  
  As all House of Commons speeches are written down in Hansard for posterity, this means one of Stormzy's grime lyrics is now a historical record.
• The music video, directed by Daps, includes a cameo from Stormzy's fellow South London artist Raye. That's her at the start of the visual standing on the right-hand side wearing a blue Adidas jacket.
