twacked out 

when you've been up for forever on meth and are starting to trip hardcore - ie, when your face is beginning to become one giant open bleeding sore from picking at it.

"damn, i am so twacked out, i plucked until i dont have any eyebrows left."
"your pupils are so big you dont have any color in them - you're hella twacked out."
"for the last time, that is a MINIVAN, not the FBI - quit getting so damned twacked out!"

tackhead 

This is a word often used to describe an individual (more specifically a lower-income female from the inner city) that is loud, tacky, boisterous, and not used to the finer things in life.

TaShaNe is truly a tackhead. She went to red lobster and asked in a loud ghetto voice for an order of "scrimp." After that, the tackhead asked "Do ya'll take EBT cards up in here."
