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

'reminder' is the definition.
(I've seen this before)

I can't explain the remainder of the clue.

(Other definitions for nudge that I've seen before include "suggestive move" , "Gentle poke with elbow" , "Gentle encouragement" , "Prod gently with elbow" , "Light touch or push" .)

I've seen this clue in The Globe and Mail.
