An alternative even more accurate name for a fifth wheel or a trailer hitch on a semi. This name is derived from the fact that a properly maintained towing apparatus must be gooed up with grease, and the trailers connected to them are long. Plus it's fun to say.
That idiot trucker's trailer came off on the I-90 because he didn't properly grease his googlong.
