Squinch /skwɪn(t)ʃ/
To lovingly squish.
To squash, squeeze, pinch etc in a non-harmful way, out of love for the squinched one. Think of an aunt or grandma pinching a baby's cheeks, she "squinches" their cheeks.

Used in reference to acts of "cute aggression".
"I just can't wait to squinch his lil' cheeks!" or "Imma squich you!" then launch yourself at your much beloved partner.
