A mysterious weather pattern that has repeatedly caused a man's wallet to disappear without trace, usually ocurring while the man is drunk on russian vodka.
Mate.1 - "Holy fuck Ansen you've lost your wallet on the train from Siberia to Mongolia, that's pretty fucked up."

Mate.2 - "Yeh I heard on the news that the mongohole was heading our way, but didn't realise it would hit so early!"

Mate.1 - "You knob"

Mate.2 *Headbutts the wall*
