Get all worked up (6)
I believe the answer is:
seethe
'get all worked up' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for seethe that I've seen before include "Ferment, sizzle" , "Of water, bubble or surge as in boiling" , "Bubble, almost boil" , "Bubble gently like boiling water" , "froth" .)
