It derives from the Jamaican words rahtid and (sometimes) rarse. It’s a versatile Jamaican Patois Exclamation that means "wow," "damn," or "oh my god".
And in some regions like the Midlands it also means “really”.
It’s British Jamaican culture.
Things in your pockets when you have a nice outfit on ruin it.
Money
Keys
Hand sanitizer
Hand cream
Vaseline
Gum
Different cards
Space for if I need to put anything in there
But I try to avoid my pouch as much as possible so will just have gum, cash and keys in pockets
