TB technically means "teeny bopper". This term refers to not only girls but the male gender also. It refers to kids who are immature and have no common sense or maturity. They also type like this "HeYoOoOSHieszz" They tie their hair up in a way which only little kids tie their hair, and wear clothes which are out of taste.
