Manage to do it across the pond (4,3)
I believe the answer is:
make out
This clue is a double definition.
'manage' is the first definition.
(thesaurus)
'do it across the pond' is the second definition.
(US term meaning to have sex)
'to' acts as a link.
(Other definitions for make out that I've seen before include "Discern" , "Manage to see" , "understand" , "Distinguish; pretend" , "Descry - succeed" .)
