Laugh, getting a kiss for practical joke (4)
I believe the answer is:
hoax
'practical joke' is the definition.
(practical joke can mean a hoax or trick)
'laugh getting a kiss' is the wordplay.
'laugh' becomes 'ho' (representation of a laughing sound).
'getting' means one lot of letters go next to another.
'kiss' becomes 'x' (X can represent a kiss).
'ho'+'a'+'x'='HOAX'
'for' is the link.
(Other definitions for hoax that I've seen before include "Scam" , "Playful fraud" , "A fraud or deception" , "Deceptive trick, could be malicious" , "Practical joke" .)
