Heave with laughter on 2nd-3rd of July (4)
I believe the answer is:
haul
'heave' is the definition.
(thesaurus)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for haul that I've seen before include "Pull forcibly; catch" , "Yank" , "Pull or drag forcibly" , "Drag; transport in truck" , "Drag; quantity of fish caught" .)
