To lose a game without scoring a single point. Often used in card games and sometimes reffered to as Black Nuts. Usually there may be a rule in place, that if u are "Black Balled" u cant play anymore for 3 to 7 days. Therefore labeling you as Banned!
Identical to the youtube event in which one is "Rick Rolled" with the exception that instead of "Never Gonna Give You Up" by Rick Astley, one is subjected to the song "Friday" by Rebecca Black.
Person-"Hey did you see the new Transformers trailer?"
Other Person-"Not yet"
P-"Dude its fucking sweet, gimme a second"
(video begins to play Friday)
P-" WTF!?!?!?!"
OP- "dude, you just got black balled"
