Smith Collapse
In Poker, when someone is leading the chip lead for most of the night, then, when the tournament is close to the end, the unfortunate donkey unwittingly plays with so much overconfidence that they go all in with a semi-decent hand and get outdrawn to lose their stash.
Holy Ace of Spades, Karl was victimized by the ole' Smith Collapse again...that's the third poker tournament in a row that he blew his load all over the poker table. What a donkey!
