"Riffraff" is an English term that dates back to the early 14th century, originally from Anglo-French rif et raf, meaning "every scrap" or "odds and ends." It was first used to describe the sweepings or refuse of something, and then applied metaphorically to people considered the dregs of society. Over time, it came to mean a group of people seen as low-class, undesirable, or disreputable. The term is derogatory, used in informal speech, literature, and commentary to express social disdain, and it targets groups rather than individuals.

A seesaw is a playground device consisting of a long board balanced in the middle, with a seat on each end. Children sit at either end of the board, and when one child pushes off the ground, the other side rises. The motion is similar to going up and down, with each side taking turns to lift and lower. Seesaws are often found in playgrounds, encouraging children to work together, as they need to coordinate to keep the seesaw moving smoothly. They help develop balance, coordination, and social interaction while providing fun and active play.
