pinch, between

Mnemonic

Your hand darts into the tank to grab a lobster, but the creature retaliates — clamping its enormous claw around your finger in a brutal pinch! Now you're pinching the lobster and the lobster is pinching you right back. Neither side lets go in this savage pinch standoff.
Additional thoughts
Visualize the symmetry: your hand squeezes the lobster's body while its claw squeezes your finger — both sides applying pressure from two surfaces, perfectly capturing the sandwiching/clamping meaning of this kanji.
Quick recall
Your hand grabs a lobster and it pinches you right back.
