TI

The act getting busted by the ATF for buying illegal machine guns and silencers either by
(1) Doing it yourself
(2) Hiring a bodyguard to do it for you - all because you are a convicted felon who cannot own guns.

Puff Nappy's eyes got REAL BIG when he was suddenly "TI'ed" as he took possession of those illegal machine guns he purchased to take back to da hood.

Ti ti chou pi yi

1. Slang phrase in Mandarin Chinese for one who believes his or her friends are telling the truth regardless of how ridiculous and preposterous the things they are trying to tell him or her are.

2. One who gives his or her friends bragging rights to exclusively tease them for endlessly searching the Interweb for the definition of phrases.

Stewy: "Hey what does ti ti chou pi yi mean?"
Adeline: "We can't tell you... look it up online!"
Stewy: "Ok. (one hour later) I still can't find it, is it spelled differently? I'm so confused."
Adeline: "muahahahaha"

Ti'Yuana

a person who's been through a lot in her life but came out very strong . she's bipolar but she has a little heart . she has been let down plenty of times , but she never let anyone down . she may have not been there , but it wasn't her fault . people continue to push her away , that's why she doesn't reach out to people as much anymore . she's staying away from negativity and b.s. she's focusing on school and that's pretty much it .

Ti'Yuana has put up a wall so no females wouldn't hurt her!

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!"
