A delicious sandwich, that consists of sub bread, (6 inch only), pickles, salami and swiss cheese. Preferable order: cheese salami, pickles. The sandwich MUST be toasted to qualify as a Nicholas.
"Oh shit The Nicholas that I had for lunch was so good."
"All the food at school today is shitty, let's just get some Nicholi."
"That Nicholas was dank as shit."
"Fuck bitches, eat Nicholases."
