The word you say while your brain searches for the word you meant.

means Material added mainly to take up space or time, rather than for its own value — the 'um,' the padding, the stuff between the good parts.

from Straightforward agent noun from 'fill,' which traces back to Old English 'fyllan,' rooted in Germanic 'full' — the idea of making something full. 'Filler' as a word for padding material (speech, writing, even dental work) is a natural extension that shows up once people needed a name for the stuff that occupies space without being the point.
