This name is for the girl that shares so many qualities with the GMC Sierra. No matter the load, big or small, you can just throw that shit in the back and she'll take it.

Sturdy, reliable and a good all rounder.
Damn, would like to see what I could fit in that sierra before the wheels blew out

Sierra’s are typically crazy. Like nuts, bonkers, insane. But that’s okay cause they make life interesting. Usually they’re gay af, GINORMOUS fangirls, and have the dirtiest and evilest mind you could ever imagine. They’re also really short. And loud. And almost scary, especially when playing soccer. Which they’re a kickass goalie by the way. Sierra’s are also the ultimate Slytherin, like even their patronus is a snake.
Sierra: HOLY SHIT GINNY WEASLEY OWNS MY ASS FUCK YOU GOATMAN

A girl who has an obsessive crush on someone, so obsessive to the point where she'll stalk them. The term originated from a Total Drama World Tour character named Sierra.
That girl has a shrine of him, she's such a Sierra.
