worm

The word evokes a visceral sense of wriggling, softness, and subterranean movement. In its literal biological sense, it often carries connotations of decay or earthiness, though not always negative.

When applied to technology, the term shifts toward a feeling of invasive, stealthy persistence—something that burrows into a system unnoticed and spreads autonomously.

In a social context (the verb form), it is almost always pejorative. It suggests an opportunistic, slippery, or manipulative approach to gaining access or favor, implying a lack of transparency or honor compared to "earning" one's way in.
