Applaud - yes, one goes wild, see (4,4,2)
I believe the answer is:
clap eyes on
Here is my best explanation:
'see' is the definition.
'applaud yes one goes wild' is the subsidiary indication.
'applaud' becomes 'clap' ('clap' can be a synonym of 'applaud').
'goes wild' is an anagram indicator.
'yesone' is an anagram of 'eyeson'.
(Another definition for clap eyes on that I've seen is "Catch sight of".)
