Dirty EastEnder headbutts, in return getting floored (7)
I believe the answer is:
stunned
'floored' is the definition.
('stun' can be a synonym of 'floor')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for stunned that I've seen before include "Knocked out; astonished" , "Stupefied" , "Dazed; astonished" , "Amazed" , "Taken aback" .)
