TI

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!"
