👉 "Mound building" is like when a bunch of archaeologists decide to construct a grand, ancient-looking pyramid out of dirt and rocks, but instead of being buried, it's more like a giant, earth-filled joke monument. It's the art of creating a hill or a pile of earth, usually with no real purpose, just for show.
Here's an unsettling example sentence: "The eccentric billionaire decided to mound build a monument to his lost love, complete with a sarcophagus made from his own broken vase collection."
