Disneyland Inch
The extra mark-up on Disneyland (and other) products that change an expensive but reasonable ass-raping purchase to an insulting and humiliating ass-raping purchase. Excessive profiteering that ultimately results in the loss of the sale.
I was willing to bend over to buy the Indiana Jones Hat, but the bastards added the Disneyland Inch. I couldn't justify getting ass-raped that extra inch, so I didn't buy it.
