A shortened version of the word suicidal. It is used as an exaggeration, not to be taken serious. Usually the word will be used as a complete overreaction to what actually happened.
"Im su the Cowboys lost."
"Im su I didn't get french fries with my burger."
"Im so su about going out to eat with him tonight"
