pullulating

Swarming with life

Pullulating means teeming, swarming, or breeding abundantly.

The word suggests rapid multiplication or proliferation, often with connotations of organic growth pushing outward: pullulating crowds filled the streets, the pullulating mass of bacteria.

It can describe anything breeding or spreading vigorously—insects, ideas, rumors, or urban sprawl.

The tone is typically vivid and slightly literary.
