Ear Balling
Ear balling is when you use both your eyes and ears at the same time. Like when you watch a concert and listen to the music at the same time. It’s like being super focused and not being a total idiot.
'I used ear balling to know when the beat drop was coming.'
'She did ear balling and got the best seat in the house.'
'He used ear balling to cheat at the karaoke battle.'
