Online gamer's woe (3)
I believe the answer is:
lag
'online gamer's woe' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lag that I've seen before include "Convict (slang)" , "Loiter" , "Prisoner" , "Fall behind or cover to prevent heat loss" , "Fall behind; insulate" .)
