香港巴士術語，指嗰啲行車路線好長，幾乎每個巴士站都有乘客上落嘅巴士路線。呢啲路線通常歷史比較耐，係以前道路網絡未咁發達嗰陣嘅產物，經過多年嚟合併其他路線而變得越嚟越長。乘客通常只會搭幾個站，好少會坐足全程。 (Hong Kong bus slang, refers to a bus route that is very long and has passengers getting on and off at almost every stop. These routes are often long-established, a product of a time when the road network was less developed, and have become progressively longer over the years through mergers with other routes. Passengers typically only travel for a few stops rather than the entire journey.)
