Instahate

When you instantaneously or spontaneously know you hate someone or something.

I was overcome with instahate the moment I saw my ex's newest conquest.

I instahated her the second our eyes met!

Instahate

Someone you hate on Instagram. You don't even know them in real life but still, there's this feeling of hate.

Oh you know, she's friends with that girl I instahate.
