highschool habits die hard

[YDK]

So there's some shit on Facebook with a few people that I graduated with trying to set up a 10 year class reunion. Everybody's like "o shit I feel so old" and "I can't believe how fast times flies" and the standard bullshit.
I'm like "I can't help I'm too unorganized for that shit but I'll come and get drunk"

Then this bitch posts

A bitch that we gave the nickname mafisha (Marissa) because she stunk all through middle school an shit. She was annoying as fuck forever
Like fat ugly stinky with the confidence of a fuckin goddess
She really needed to be brought down a few bugs

Anyways
She posts like " O wow where did all the time go!?"
And I instantly respond "looks like you waist you fat bitch"

Now
This is ten fuckin years after we graduated
We're supposed to be grown an shit

She's married (poor guy) with kids, so am I, so are most of the class

But I automatically responded calling this cunt a fat bitch the first time I even hear her name in ten years
I almost felt bad
But I was like
Fuck it, the bitch needed to be reminded of her place in our school

So I left it there

Waiting for a response now
