Originally derived from the mishearing of the phrase "shotgun not", in the instance of which, the mishearer may enquire as to what the term means declaring they have mistaken it for 'sugarnut'. In the present day it essentially acts as a general purpose inquiry and is virtually interchangable with "What?".
"What is all this sugarnut shit?"

A "pet name" of an adored or term of endearment for a significant other who has deliciously suckable, irresistible balls.
I use the name "Sugar Nuts" to refer to my Sweet-thang Aaron whose balls I could lick all day.
