means Soft, yielding, and pleasant to press, so it gives way under your fingers and springs back rather than holding firm.
from From 'squish,' an imitative word — your mouth practically makes the sound when you say it, that wet 'squ-' of soft matter compressing. English has a whole family of these 'squ-' words for moist, mushy actions (squash, squelch, squirt, squeeze), all echoing the noise of giving things giving way. Add the '-y' that turns a thing into a quality, and you get 'squishy': having the property of squish.
