三歲 [sān suì] n. Three-year-old. This Internet slang term is often coupled with someone’s last name. It became popular first when used to describe Hong Kong actor Francis Ng aka Wu Zhenyu when he appeared with his son on the reality TV show Where Are We Going, Dad in 2014. Netizens dubbed him “Wu Three-Year-Old”, amused by his mischievous and childlike personality on the show as well as on Weibo. The meme has been widely used to describe many beloved celebrities.
