晃荡

• ピンイン: huàng dang
• 漢字の分解: 晃 = 日 + 光 (sun + light, originally dazzling; extended to swaying); 荡 = 氵+ 汤 (water radical, flowing/rocking)

意味

（ゆらゆら）揺れる；（目的なく）ぶらぶらする

Has two main uses: a physical sense of something swaying or rocking back and forth, and a colloquial sense of a person wandering or loitering aimlessly without productive activity. The physical sense is more neutral; the aimless wandering sense often carries a mildly negative connotation.
