greaser

plural greasers

1. Someone or something that greases (applies grease).

   The pole was greased and men tried to walk out to the end of it and dislodge the crate. The pole was supple, the crate swayed as each man crept out clinging desperately and finally fell off into the sea. […] People roared with laughter and greasers applied fresh grease for the next person's try.
