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

'aim when expectorating' is the definition.
I can't judge whether this definition defines the answer.

'points to different' is the wordplay.
'different' is an anagram indicator.
'points'+'to'='pointsto'
'pointsto' is an anagram of 'SPITTOON'.

Can you help me to learn more?
