Similar to the Rickrolled internettrick, where an unsuspecting websurfer is forced to watch a Rick Astley music video while on an internet forum, message board, etc. However, being Blackrolled involves the substitution of Rebecca Black's video "Friday" instead.

A very mean and rude friend sends you a youtube link to Rebecca Black's Friday.
You are at a party and everyone is dancing to some dubstep and then you ninja the next song to Rebecca Black's Friday...AKA BLACKROLLED! (Even better to do on a day that is not Friday)
