To bamboozle is to hoodwink, lead by the nose, or pull the wool over someone's eyes — you're tricking or fooling them.
Bamboozle may sound like a funny word, but anyone that's ever been bamboozled could tell you it's nothing to laugh about. A bamboozler lies and pretends to be a good guy, all the while plotting to empty your bank account or steal away your promotion. Con men are professional bamboozlers. Some people think advertisers are bamboozlers, since they're constantly trying to trick you into buying something you probably don't need.
