Noah

A Noah is someone who you fall head-over-heals for, kind of like a first crush but on crack. A Noah causes you to lose your mind and common sense as you quickly become infatuated and obsessed. A Noah will come out of thin air and while it might confuse others at first, Noahs are inevitable and you will one day fall into their trap. No matter how hard you try to forget, a Noah will NEVER go away.

"Do you remember that time you hardcore crushed on and stalked ____?"
"Yeah, he's my Noah."
