'clinging to frame' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'poor rowers head off' is the wordplay.
'poor' becomes 'skint' (similar in meaning).
'rowers' becomes 'eight' (I've seen this before).
'head off' means to remove the first letter.
'eight' with its first letter removed is 'ight'.
'skint'+'ight'='SKIN-TIGHT'
