A preposterously large amount of something. Greater than a boatload but less than an asston.
I'm totally stoked because I just ate a jazzload of nachos. My friend, on the other hand, is not stoked, because he ate and asston of nachos and horked up all over the water closet.
May I have an order of regular degular buttermilk pancakes? Without all the added jazz? Hold the blueberry smiley face, strawberry glaze, chocolate chips and whipped cream.
