To defy all odds by finding defeat in the face of certain victory. To fuck up royally. Choking in its finest form. Made famous by the Minnesota Vikings football team (see 1999, 2010, 2016 playoff games).
Did you watch that game? Minnesota had a chance and then they totally viked up at the end.
I knew the Vikings would vike up that easy field goal.
We had the lead the whole game until Adrian Peterson viked up and fumbled.
