Ultra Sangria: A wine/or product/or person that is so old, flawed, or disgusting that even the "Sangria treatment" can't save it.
Dude #1: "I chilled it, added fruit, peppered it, herbed it, splashed it with Vodka and I still can't drink this sh*#*t!"
Dude #2: Whatever! its "Ultra Sangria"... it's not toxic, so just shut up and drink it!"
Or: "Man, I tried everything, I even medicated myself. I can't deal with her! This chick is Ultra Sangria!"
