Chucks slob out (4)
I believe the answer is:
lobs
'chucks' is the definition.
The answer and definition can be both to do with contact as well as being verbs in their -s form.
Perhaps there's a link between them I don't understand?
'slob out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'slob' is an anagram of 'LOBS'.
Can you help me to learn more?
(Other definitions for lobs that I've seen before include "Sends over a high ball" , "Pitches" , "chucks up" , "Throws ball slowly in high arc" .)
