When the new porn you're downloading is 5% from completion and the download speed drops considerably or stops completely.
It was just about beat time when my shitty service provider totally eCock-blocked my Jenna Haze download.

1. When you are about to watch porn, and right as the video loads, you get an Instant Message (AIM, MSN, YAHOO, etc) that blocks the video.

2. The same instance of getting an IM, but right as you start to orgasm from masturbating while watching porn.
Oh my god, I was watching some great lesbian porn when I got e-cockblocked by my friend!
