from the legend of the Mexican mythical
bird beast that would come to collect the souls of the dying, a term for a girl that is irrefutably
ugly- almost to a humorous extent when they think they're pretty. Usually have very low self-esteem and only succeed in finding significant others by promiscuity. And even then, they don't stick around long. "L.C." for
short.
"You see that girl check you out, buddy?"
"You
mean that la chusa, dude?"
"Hahaha well she's not the prettiest..."
"
Don't
call a LC a 'she'. Try 'it'."
