means To press something firmly from opposite sides, often to extract liquid, force it into a tight space, or hold it tenderly.

from From Old English 'cwȳsan,' meaning to crush or press, with the initial 's' creeping in later — likely an intensifying flourish, the kind of sound-stretching that makes 'crash' feel bigger than 'crack.' The romantic sense, 'my main squeeze,' is a 20th-century American slang bloom, turning the act of pressing into the act of holding someone close.
