抽水 (2) to promote ... by taking advantage of the topical person or issue

"抽水"有幾個意思:

(2) 用於傳媒或廣告方面, 藉着某熱門話題, 加上自己的意見或者材料, 來增加自我宣傳效果

to promote ... by taking advantage of the topical person or issue

e.g The merchant promotes his products by taking advantage of the sex scandal.

廣告界的 borrowed interest 的 jargon 適合去翻譯這詞語 "抽水"
