"Bye-bye" muscle sounds very funny. Actually when you say good-bye to someone, you will shake your hand highly. Then look at your arm, do you see your "bye-bye" muscle is also shaking?
It "sounds" very funny, but sadly, it is strongly attached to my body. It makes my arm looks "fatter" and more bulky than it actually is. I would not like to wear my basketball vest with this bye-bye muscle.
