"Vitriolic."
Yes, it's a good word. Interesting, eye-catching even. But I've seen it an awful lot in the last few days and I think it's time we collectively exercised our vocabulary to come up with a few good alternatives.
Something like:
Nasty.
Mean.
Caustic.
Hateful.
Antagonistic.
Hostile.
Rancorous.
Acerbic.
Acidic.
Acidulous.
Antipathic.
Full of Animosity.
Vindictive.
Loatheful.
Malignant.
Bitter.
Spiteful.
Bile-laden.
Malevolent.
With malice.
Come on, people! Let's get creative!
