Tip it playfully over an officer! (4)
I believe the answer is:
tilt
'tip' is the definition.
(synonyms)
'it playfully over an officer' is the wordplay.
'playfully' is an anagram indicator (I've seen this in other clues).
'over' says to put letters next to each other (in a down clue, some letters go over others).
'an officer' becomes 'lt' (abbreviation for lieutenant).
'it' anagrammed gives 'ti'.
'ti'+'lt'='TILT'
(Other definitions for tilt that I've seen before include "Lean, slope" , "Joust; bias" , "Slight inclination" , "Slope; joust" , "Lean sideways" .)
