A mispelling of emo. Adding the 'r' and over exaggerating the 'oooo' adds a comical hint to the sterotype of a emo. It then becomes a joint word of emo and a cow which is comical in itself and not the least bit meant to cause offence to a "emo" or a "cow" =
*person with large hangover lays across mates bed writing lyrics on her arm because she cant afford and hasn't got any paper*
*friend walks over and starts to write emo across arm but hungover aswell mispells it as ermoo*
*friends collapse in giggles for a long time*
