Little known fact, the word began being applied to marketing after Andrew Moray's speech at the Battle of Stirling Bridge (attributed to William Wallace in the movie Braveheart). Scotland's Slughairmiers were so inspired by his cry of "Alba gu bràth" that they began to embroider it on the slughairms (using spider silk). The trend caught on. On reading the embroidered message on a slug's jacket or hat, people would so often remark something akin to "that's a really nice sluaghairm" that the word began to apply to the message rather than the ghairm itself and this evolved into our modern "slogan".
