Beat it around the back of house and laugh (6)
I believe the answer is:
scream
'laugh' is the definition.
(scream is a kind of laugh)
'beat it around the back of house' is the wordplay.
'beat it' becomes 'scram' (I've seen this before).
'around' means one lot of letters goes inside another.
'the back of' says to take the final letters.
The last letter of 'house' is 'e'.
'scram' enclosing 'e' is 'SCREAM'.
'and' is the link.
(Other definitions for scream that I've seen before include "Call for" , "'Loud, high-pitched cry (6)'" , "Person who seems extremely funny?" , "one causes great amusement" , "funny man" .)
