Ejected from taps (4)
I believe the answer is:
spat
'ejected' is the definition.
The answer and definition can be both related to bodily activities as well as being past participle verbs.
Perhaps there's a link between them I don't understand?
'from taps' is the wordplay.
'from' indicates anagramming the letters (from the letters).
'taps' is an anagram of 'SPAT'.
Can you help me to learn more?
(Other definitions for spat that I've seen before include "Gestured with contempt" , "Pat's involved in petty quarrel" , "Minor difference" , "Small altercations between Pats" , "Taps in minor quarrel" .)
