stunlock

To render (a character) unable to move or react by repeatedly hitting them and keeping them in a stunned state.

I got stunlocked by that boss's electric attack and died.

To make (someone) freeze, not knowing how to respond or react, by doing something unexpected or shocking.

In his labcoat, his phone buzzed. Stunlocked by Karen's furious glare, he pulled it out.

A stunned state of this kind.
