Does it smell like
pus?
I had this big blackhead on my neck one and sometimes when I scratched it a miniscule amount would emerge from the bump.
Gross, yes I know but anyway the stuff in there has a distinct smell which I would always notice on my fingertip.

And how will Brexit help with your fingers? Explain that, if you can.

No, it smelt like the sweaty part between ones arsehole and ball sack. Maybe I put my finger there, I don't know I can't remember.
