What it means
A proper London brush-off that means forget it, dead that, or stop talking about it. You drop allow it when someone's suggesting a mission that's long, keeps pushing their luck, or starts moving too beg. It can sound jokey or proper sharp depending on how you say it, but either way it's a neat little nah with weight.
