As Christine said, it is a term used for a type of paperweight design. I have never seen it used in respect of other glass items, which if they have a similar design would be more simply called "looped", "gadrooned" or "feathered".
It could have be a variation of the French marbre, but I do not know the actual source of the term.
In the paperweight design it is usually a pulled pattern in four, or occasionally six, loops and normally with multi-coloured threads. The loops are worked to the top of the dome and capped with at least one millefiori cane to cover the join of the loop threads.
Earliest examples are (probably) from the French Saint Louis factory of the 19th century. Several examples can be found on the Internet, but here is one in a Bonhams Auction page
