verb / noun
squish
SKWISH/skwɪʃ/
To compress a soft object.
The fingers squish the soft sponge, squeezing water from its flattened body.

Etymology
Squash means “crush or squeeze”; squish is probably a variant, perhaps influenced by obsolete squiss, “squeeze or crush.” The soft-flattening sense continues that basic action.
In context
I pulled my belly button in and I'm flattening that back down, I am squishing the strawberry. So, picture that in your mind, you're going to squish the strawberry.
