Revive streaker with tattoo on foot (4,2)
I believe the answer is:
come to
'revive' is the definition.
(I know that revive can be written as come to)
'streaker with tattoo on foot' is the wordplay.
'streaker' becomes 'comet' (something which 'streaks').
'with' says to put letters next to each other.
'tattoo on foot' becomes 'o' (I can't explain this - if you can you should believe this answer much more).
'comet'+'o'='COME TO'
Can you help me to learn more?
(Other definitions for come to that I've seen before include "Regain consciousness or arrive at" , "Wake up" , "cost" , "Start fighting" , "Regain consciousness - stop vessel" .)
