look up any word, like fleek:
Usually refers to health nuts. They are afraid of carbs and like wheat bread.
The Halliday's went to the store and bought health nut bread.

Forever alone.

The very personification of Forever Alone: no-one will ever be just as lonely as a Halliday.

He or She will never be loved, never be held, and absolutely never go on a date.
You see that guy who hasn't left his room in weeks because no-one will Love him?

SUCH a Halliday
