The word "炫弄" is formed by combining the character "炫", which means to show off or display something brightly, with the character "弄", which means to play with or manipulate something. Together, they create a verb that specifically denotes the act of flaunting or parading one's abilities or possessions in a boastful manner, where "炫" conveys the display aspect and "弄" adds the sense of handling or manipulating something to demonstrate skill.
