1.
Something so incredibly horrible. Can also be used to describe how you feel. Commonly a modification of the phrase "when the shit hits the fan", replacing the "fan" in fantastic with "shit" making up the combination "shittastic"
"That test was so shittastic, I'd be lucky to get a 20%!"

"Ugh, I'm so hungover I feel shittastic."
