How to answer this bitchy question?

[Georgie]

On instagram i tag my photos stuff like #instagood and #instalike
Well my friend (who i think hates me) commented why do you hashtag #instagood and #instalike (obviously in a mean way i know she meant it like that)
I dont want to be mean back so how should i answer her?

[Primrose :$]

Just be like, "If you got a problem, please stand aside with the rest of people waiting for me to care what they think about what I do." She's not a friend, she's a bully.

[yo homies]

Just say "and why do you care?"
She's using you so she can degrade you to make her seem cool. She thinks that by making you seem stupid or something, people will like her. I seriously hate people who publicly try to humiliate someone for their own benefit.
