Go rollerblading (5)
I believe the answer is:
skate
'go rollerblading' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for skate that I've seen before include "Edible marine fish" , "Recite Keats badly to the fish" , "Fish of ray family" , "Large edible ray" , "Takes off like large flatfish" .)
