I believe the answer is:

thirsts

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

'is lacking water' is the definition.
I can't tell whether this defines the answer.

'this outside right on the street' is the wordplay.
'outside' is an insertion indicator.
'right' becomes 'r' (abbreviation).
'on' is a charade indicator (letters next to each other).
'the street' becomes 'st' (abbreviation).
'r'+'st'='rst'
'this' placed around 'rst' is 'THIRSTS'.

Can you help me to learn more?

(Other definitions for thirsts that I've seen before include "Cravings" , "needs water" , "Hungers!" .)

I've seen this clue in the Sydney Morning Herald.
