Ragamuffin staggering out of bounds (6)
I believe the answer is:
urchin
'ragamuffin' is the definition.
(I've seen this before)
'staggering out of bounds' is the wordplay.
'staggering' becomes 'lurching' ('lurch' can be a synonym of 'stagger').
'out of bounds' means to look at the middle letters (the bounds or edges of the word are removed).
The centre of 'lurching' is 'URCHIN'.
(Other definitions for urchin that I've seen before include "Gamin" , "Poorly-dressed child" , "Mischievous or ragged child" , "Mischievous child and hedgehog" , "Young troublemaker" .)
