Chuck from Heathrow (5)

I believe the answer is:

throw

I'm a little stuck... Click here to teach me more about this clue!

'chuck' is the definition.
(I know that chuck is a more specific form of the action the throw)

I cannot understand how the rest of the clue works.

(Other definitions for throw that I've seen before include "Try to lose" , "Dumbfound" , "Discard" , "Make a pot" , "A turn with the dice" .)

I've seen this clue in the Evening Standard.
