Bamboozled!
The act of tricking one into or otherwise causing someone to go for a low five. From which, you pull your hand away at the last second and shout "Bamboozled!"
I hold out my hand and say "low five dude." My friend then goes for said low five raising their hand high in anticipation, just to have all of it ripped away at the last second as i pull my hand from the fiving-zone and yell "bamboozled!"
