‘Lang may your lum reek’….what does this mean? ‘Lum’ is the Scottish word for chimney. If your lum reeks, no, it’s not smelling bad, it’s got smoke coming out of it! Historically, only the wealthy could afford to have their fires burning continously, so here in Scotland we say this to wish people health, wealth and happiness in their new homes. A unique and very Scottish new home gift.
