Plank

plank, board, plate, stage

Mnemonic

A tree goes full anti-establishment, refusing to stand upright in the forest any longer. It hurls itself to the ground and demands a lumberjack saw it into a flat plank. The most rebellious tree becomes the finest plank in the whole lumber shop.
Additional thoughts
Picture a defiant tree toppling itself on purpose, insisting on being reshaped into a smooth, flat board. Anti- attitude + tree material = plank.
Quick recall
An anti-establishment tree throws itself down to become a plank.
