A combanation of "hack" and "tackle" which defines an over zealous challenge in football/soccer.
"Oh Dear, that chap seems to have been badly hackled there, look here Ref send that unsporting ruffian off."
Hackle: When someone both cackles (laughs) and hacks(coughs) at the same time.
I think that dude is going to die. Do you hear his hackle? I think he's going to hackle up a lung.
