Example: The hat slipped down until it covered her eyes.

When someone or something moves without wanting to move, we say it slips.

Example: My foot slipped when I stepped on some ice, and I almost fell.

When someone moves quickly and quietly so that other people won't see them move, we say the person slips.

Example: I slipped into the kitchen to start washing dishes while people were talking.
