Nicknames thread: what do traders call the pairs?

Cable, fiber, loonie, aussie, kiwi, swissy — traders rarely use the official pair names, and news headlines assume you know them. Beginners meet these nicknames on day one and nobody explains them.

Post a nickname and the pair it means, one per reply, or ask about one you've seen. The community can build the most useful thread for new members this forum has.

The currency pair nicknames guide collects the common ones with their origins.
