greaser

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.

... incidentally, our correspondent tells of a West Indian who applied for a job at Kings Cross as motion greaser - but with no idea of what he would have to grease and why. Invited to find out and return within a month, he did, and nowadays the Kings Cross engines are as efficiently greased as any on B.R.

A mechanic.

A biker, a tough.

A rocker or metalhead, especially one who listens to 1950s rock and roll or 1980s thrash metal.

By such standards, the Greasers are pretty minor stuff. Basically, they're just the 1970 version of that time-honored English figure, the Leather Boy. During the fifties, he was known as the Teddy Boy; in the early sixties, he became the Rocker; and now, after a couple of earlier attempts at revival, he's back yet again, the Greaser.

A very soft landing.

A surname from German.
