A person who has a strong devotion to God and Jesus and who loves to read the Bible before bed. In their spare time, Sieras like to run naked through pastures filled with llamas. Sieras are basically amazing and hella gangsta.
"Damn you Jesus!" -Siera

A bitch ass whore who likes to steal your boyfriend.
She's a ratchet that cant get a guy, so she'll try to steal yours.
She also spreads rumors. If you know a siera, ditch her bitch ass.
She's stupid, ugly af and cant sing or dance.
On a scale from 1-10 shes like a -9000
"Dammit here comes that bitch siera. I HATE her!"
