Birdlime \Bird"lime`\, n. [Bird + lime viscous substance.]
An extremely adhesive viscid substance, usually made of the
middle bark of the holly, by boiling, fermenting, and
cleansing it. When a twig is smeared with this substance it
will hold small birds which may light upon it. Hence:
Anything which insnares.
