Go away! Shout loudly to remove European (5)
I believe the answer is:
scram
'go away' is the definition.
(scramming is a kind of going away)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for scram that I've seen before include "Clear off!" , "Make oneself scarce" , "Go away quickly" , "make emergency shut-down" , "Beat it, get lost, go away" .)
