look up any word, like slope:
Astronomical fail. Something going so wrong as to require an extra adjective (astronomical) to accurately describe how terribly awful something went. Can also be used to describe a person who fails at something or just life in general.
"Dude, that part last night was an astro fail."
"You clearly can't dance. Astro fail."
"You are such an astro fail sometimes."
