New Jack 

Short for the word New Jack Swing, used för the music genre that had its biggest years in the late 80's until the mid 90's. It is a hybrid of R&B and sounds like hip hop with a more "swinging" sound on the beats, with the r&b style of singing.

Teddy Riley is said to be the father of New Jack Swing, also Tony Toni Toné, Johnny Gill, Gerald Levert, Bobby Brown, Blackstreet, New Edition and Guy were big names in the New Jack era.
The movie New Jack City (1991) also contains a lot of New Jack Swing music.

"Don't believe a thing about the New Jack Swing!"
-Teddy Riley

The Jack Talk Thai 

A method used when trying to detect the authenticity of another person's story. Take two fingers and apply in to the wrist pulse area. This is all done for effect for if the subject is uncomfortable with what they are relating in any way they should betray themselves.

I used the Jack Talk Thai on Andrea and was fully satisfied when she unflinchingly repeated her entire alibi with utmost poise. The only downfall of this reassuring procedure was that I was relegated to the couch for the night.

Taco Jack 

An amazing creation from the Value Menu at Jack In The Box. You start with Breakfast Jack and the 2 Regular Tacos, each 99 cents. You split the Breakfast Jack between the ham and the egg and insert one of the tacos, adding taco sauce if necessary. Slap the Bfast Jack back together and enjoy that tasty 'wich!

Greg: Breakfast time!

Friend: Is that-did you put a taco in a breakfast sandwich?

Greg: Fool, this is a Taco Jack...get outta my face!
