b-switch
a person who is fast, can play ball like a pro, and sing so good it makes your brain explode, they are the best and they know it.
This b-switch just did a slam dunk and sang a song about his lunch.
My friend is a b-switch. He beat me in the game and then started singing about my hair.
That b-switch was in the gym, shooting hoops and rapping about his pants.
