the.com/gulf stream

means A warm, fast-moving ocean current that flows from the Gulf of Mexico up the eastern coast of North America and across the North Atlantic toward Europe, carrying heat and shaping climate along the way.

from From 'gulf' (via French golfe and Italian golfo, tracing back to Greek kolpos, meaning a fold or bosom — the curve of a bay) plus 'stream,' an old Germanic word for flowing water. The current was named for its origin point in the Gulf of Mexico, where it gathers heat before streaming northeast. Benjamin Franklin helped popularize and chart it in the 1700s, after noticing that American ships crossed the Atlantic faster than British ones — he got the current's shape from Nantucket whalers who already knew its path from chasing whales along its edges.
