Northern masculine male leaves to get snack (5)
I believe the answer is:
nacho
'snack' is the definition.
(I've seen this before)
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for nacho that I've seen before include "part of a snack?" , "Small piece of tortilla with a topping" , "Tortilla crisp" , "Tortilla chip topped with cheese and spices" , "Mex. corn chip" .)
