To be completely zoned out or disconnected from reality, as if floating through mental outer space. The extreme version of chronic daydreaming — you can talk to them and they won't respond.

A debt you never intend to pay, a swindle or financial scam. In Spain a pufo is when someone takes your money and conveniently forgets the whole transaction.

To completely ignore something or someone — to walk right past without stopping, paying attention, or engaging. The deliberate act of treating something as if it simply doesn't exist.

Without order, reason, or coherence — done haphazardly without any logical structure or purpose. Something done sin ton ni son is completely random and inexplicable.
