Mound
Mnemonic
The party guests needed a stage, so they piled up earth into a massive mound. Standing atop the mound, the DJ spun tracks while dirt crumbled beneath the dancing crowd's feet. The higher the earth rose, the wilder the party got!
Additional thoughts
Picture a rowdy outdoor party where revelers keep shoveling earth higher and higher, building a mound-stage. The two radicals stack visually: party on top, earth on the bottom—just like partygoers standing on a dirt mound.Quick recall
A party on a pile of earth forms a wild mound-stage.
