跩 (zhuǎi) is a colloquial word that describes a swaggering, self-satisfied manner of walking or behaving — like strutting or showing off. Although the source dictionary lists it as a noun, in natural Chinese it almost always functions as a verb ('to waddle, to swagger') or an adjective ('cocky, self-important'). You'll hear it in phrases like 跩什么 ('what are you swaggering about?') or 别跩了 ('stop showing off'). The pinyin is zhuǎi, not provided in the source row.
