RRR Racing Forum's logo on Sacred Cow.
Sacred Cow(s) was a term created by RST and used on RRR Racing Forum. It is used on people who have been around a long time and had conflicts with RRR or been some how rude to certain members of the community. As defined by RST:
"It is a person who does not want the online scene to become better, just because he/she doesn't care. Or they want to have some type of control or presence...in essence it is just a guy who wishes not to loose popularity and the like."
There was a topic on RRR called "Old Sacred Cows" on which the term was officially introduced.
The term has been mainly used by RST to disparage another person in Re-Volt scene. It has not been widely used by others than RST except as parody. The presence of a sacred cow used to be declared by RST saying "moo" in chat.
