I believe the answer is:

leer

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

'look sideways' is the definition.
'leer' can be an answer for 'look' (leering is a kind of looking). I'm unsure of the 'sideways' bit.

'stagger around' is the wordplay.
'stagger' becomes 'reel' (both can mean to move around without balance).
'around' is a reversal indicator.
'reel' backwards is 'LEER'.

'and' acts as a link.

Can you help me to learn more?

(Other definitions for leer that I've seen before include "Lecherous look" , "Suggestive or sneering grin" , "Lewd look" , "Look lasciviously at" , "Look suggestively" .)

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