Shook
Etymology
Rooted in African American Vernacular English, a nonstandard past form of shake (as in “shook up”). It appears in hip-hop — notably Mobb Deep’s 1995 “Shook Ones” — and spread as general internet slang for stunned around 2016–2017.
adjective · /SHUUK/
Profoundly shaken, shocked, or rattled — emotionally thrown off balance by something.
What it names
It names the state of being knocked sideways by news, a plot twist, or a realization — a shock that lingers in the body rather than a passing surprise. Its power is in the compression: one syllable that conveys you have not yet recovered.
Example
I found out my quiet coworker used to tour as a drummer and I was shook.
Related idea
Deeper than surprised: surprise passes quickly, while being shook implies you’re still reeling.
