flaunt
UK: flɔːnt | US: flɔːnt
vt. to display ostentatiously; to show off
vi. to behave in a way that attracts attention
The origin of "flaunt" is uncertain but may derive from an imitative or expressive root, possibly mimicking the idea of waving or fluttering (e.g., like a flag or fabric). It first appeared in English in the mid-16th century with the sense of "to display proudly." Over time, it acquired a more negative connotation of excessive or boastful display. The spelling has remained consistent, though its root is obscure.
