Dump and kick creep (6)
I believe the answer is:
tiptoe
'creep' is the definition.
(I've seen this before)
'dump and kick' is the wordplay.
'dump' becomes 'tip' (as in a rubbish tip).
'and' is a charade indicator (letters next to each other).
'kick' becomes 'toe' (I've seen this before).
'tip'+'toe'='TIPTOE'
(Other definitions for tiptoe that I've seen before include "or get a bit higher on this?" , "Go lightly and stealthily" , "Walk silently" , "Walk very lightly - musically through the tulips" , "go quietly" .)
