This can only occur when the chick you're fucking has to take a shit right before you cum. After you cum the bolus of feces begins to protrude from her anal sphincter. Once an inch or two has made its way out of her, you pull out and blow it all over that turd. That's a glazed Snickers bar.
My cousin ate a glazed snickers bar and it gave him some bad indigestion.
When you jizz in your condom when you're fucking a chick and then you dump the jizz on her head. A variation of this is the South Virginia Victory Dump. This occurs when you fuck your sister, then dump the jizz filled condom on her head.
I just took a HUGE victory dump and the crowd went wild.
