When an opponent makes a comeback and ties with first place, but the original first still wins
1)Can stand for Teen Institute, a group dedicated to helping young adults avoid substance abuse. Is somewhat similar to SADD, but sometimes people are slightly less likely to join it just cause their friends did. In some schools, TI and SADD are combined due to their similar goals.
2)Texas Instruments, manufacturer of many fine calculators, such as the TI-83 (a godsend for algebra students), TI-84, etc.
1) "They went to the TI meeting."
2) "I have a TI-83 calculator. w00t!"
That is Shit
when someone tells you that they just won a prize
TIS
A rapper who likes to whine alot
If I wanted to hear a black person whine I'll turn on Cops or Judge Judy.
TI looks and sounds like he never broke puberty.
