An embellishment that excites or stimulates: "Spritely tabasco onions, just a little crunch for the top, were an added fillip" (Alison Arnett).
One that is trivial or of little importance.
To strike or propel rapidly by as or as if by a fillip: filliped his finger against my ear; filliped the pretzel across the counter.
