Sounds to me like it will be something like Jagermeister too. If you're still alive MadduckUK, please tell us what it was!
Also, in this whole "I've tried something x%" thing, I'd just like to point out that it is either % or Proof as I've seen both being used together. i.e. a 70% Rum will be roughly 140 Proof, and it could be mean either about twice or half the strength if you get the wrong measurement!
