the.com/grease gun
A caulk gun for machinery, feeding joints the lubricant they're too proud to ask for.
means A hand-pumped tool that forces thick grease through a nozzle into the fittings of machinery to lubricate moving parts.
from Straightforward compound of 'grease' (from Old French 'craisse/graisse,' tracing back to Latin 'crassus,' meaning thick or fat) and 'gun,' used here in its extended sense of 'tool that shoots a substance out' — the same logic behind 'caulk gun' or 'staple gun.' The tool itself emerged with industrial-age machinery in the 19th and 20th centuries, once engines and bearings multiplied enough to need a dedicated instrument for forcing lubricant into tight fittings rather than applying it by hand.
