'most uncertain' is the definition.
Both the definition and answer are superlative adjectives. Maybe you can see an association between them that I don't see?

'strike stops disrupting' is the wordplay.
'strike' becomes 'clout' (clouting is a kind of striking).
'stops' becomes 'dies' (as in a machine stopping or dying).
'disrupting' means one lot of letters goes inside another (inside letters 'disrupt' the flow of outside one).
'clout' enclosing 'dies' is 'CLOUDIEST'.
