Get a move on and stamp out garrulity? (4,2,3,3)
I believe the answer is:
step on the gas
'get a move on' is the definition.
(I've seen this in another clue)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for step on the gas that I've seen before include "Drive faster" , "Hurry" , "Speed up" .)
