What does ‘shower’ mean in Uk/roadman slang?

Sounds like shower in reference to an actual shower here.

However it could be blood.. sounds abit mad tho ngl

‘Couple skengman, then showerman here
Shower man down in my shower man gear, yeah’

that’s a stormzy bar, I think it’s to do with violence but not sure exactly what

Yep deffo violence it might be some underground speak coming out of the underground into mainstream perhaps?

He says skengman here and shower man there perhaps Skeng and shower are similar.
Skeng means knife right? And knives and guns are legit the main weapons of civilian combat…
So therefire couldn’t we interpret with a reasonable degree of accuracy that ‘shower’ is referencing to the ‘spray of a gun’ where the spray of a shower is being used a metaphor for the bullet spread?

(I’m good at English lit with the quotes and stuff so I love rap and it’s interpretations)
