sillage
The trail of scent left behind by one who wears perfume.
countable, uncountable
The smell was everywhere back then, especially at college parties, which reeked of the stuff (I also remember sillage clouds of Eternity For Women hanging in the air as well). […] [Drakkar Noir] had face-melting power, with 24-hour longevity and sillage that could kill a plant.
Where it comes from
Borrowed from French sillage (literally “wake”).
