Up jack

An "up jack" is when you ejaculate into your own face and rub the semen into your nostrils.

You can up jack someone else by grabbing their penis and causing them to ejaculate into their face, at which time you rub the semen into their nostrils.

Oh man, I up jacked so much last night that everything still smells like my seed.

Scope Jack

Scope Jack occurs when a project, idea or thesis becomes all jacked up. Scope Jack typically occurs when a project, idea or thesis is clearly defined across all parties but Force Majeure or other unseen entities conspire to destroy or otherwise "jack up" the project, idea or thesis beyond all recognition of the undestood definition.

A project has been clearly defined and is all but complete when the Project Manager dies in a firey plane crash over the South Pacific. A new Project Manager is assigned to oversee the final stages of the aforementioned project. The new Project Manager decides that the original scope of work must be completely overhauled and the project, even though almost complete, must be halted, dismanteled, a new definition decided upon and begun anew. At this point the project is said to have suffered severe "Scope Jack". This normally causes the new Project Manager to be sent on a flight over the South Pacific by his or her employers to some obscure and barely known conference in a country not found on any known map.

Mr. Jack

A song from System of a Down's not so successful Steal This Album. It is the 7th song on the album. The song came from "PIG" from their Untitled Demo Tape from 1995 which also included "Flakes", "Toast", and "The Metro", which is a cover from pop group Berlin. None of these songs are in official albums. "The Metro" did however appear on the unofficail bootleg album "Storaged Melodies" which has unreleased songs from System of a Down.

"Hey Mr. Jack,
Is that the mouthwash in your eyes. Hey Mr. Jack,
Is that the cause of your surprise"- Mr. Jack, System of a Down
