Hacaca
A person who hides from everyone but you. They’re like your best friend who never shows up to the party, but you still love them.
My hacaca didn’t come to the concert, but she sent me a text saying, 'I was there in spirit.'
I told my hacaca I was going to fail the class, and she texted me, 'You’re not.'
I saw my hacaca in the cafeteria, but she didn’t say hi, she just smiled.
