you rock
[yoo rok]
What does you rock mean?
You rock is a slang phrase of praise or encouragement conveying “You’re awesome (at something)” or “You can do it!”
Where does you rock come from?
You rock ultimately evolves from rock music and the long history of the genre’s name.
Rocking and rolling was associated with the motion of ships in the early 1800s and took on sexual connotations in the 1920s, which migrated to dance music by the 1930s. Around then, popular blues songs were described as rocking, and the people who danced to them rocked.
In the 1950s, the genre of rock ‘n’ roll became fully established, as did the slang association of rock with the high energy of its sound and edgy, rebellious coolness of its social scene.
By the 1960s, the verb to rock meant “to be full of life and excitement,” and it’s this sense that has lead to you rock, “to be excellent (at something)” more generally.
