Give Up The Ghost
From The Extended Group
Originally the name of a Boston-based hardcore band, the phrase is now used as an admonition to Lukas (or anyone for that matter) who displays knowledge of which they should know little, but for which it is obvious the person is in question has researched. The saying refers to Lukas' purported ghost-like ability to go back in time and actually appear as an apparition at various historical events in which he has an interest.
Usage
It is believed the first instances of Lukas being accused of unauthorized knowledge took place in the schoolyear 2003-2004, where during a hangout in one of the breaks, Lukas casually dropped the phrase "very proud of ya" which happens to be the name of one of AFI's early records from 1996. Kevin immediately jumped accusing the man of quietly researching hardcore punk bands on the internet, then shaking his head dissapprovingly and closing the internet window quickly. Another instance came while several group members were walking in Alderwood mall, when someone said a phrase in Latin to which Lukas responded "Liberate te ex infernis" which is Latin for "save yourself from hell", the Latin version being the title for Christian death-metal band Zao's 1999 album. Kevin again pointed out that this was probably the result of Lukas' mischeivious late-night surfing. (the invokation of this Latin quote resurfaced sometime in 2004 or 2005 when the group members were watching the movie "The Event Horizon", during which Kevin made threats upon Lukas' life)
In more modern times, the quote was invented by Kevin to describe the concept of people looking through black and white live-photos of northwest hardcore bands such as Trial, Contingent, Last Man Standing, etc, and seeing a ghostly, somewhat translucent visage of Lukas standing in the shadows behind the pit. It made another brief appearance when photographs taken by Lukas at a Dillinger Escape Plan show showed "orbs" or "ectoplasms" hovering over the stage. To "ghost-hunters" these orbs may signify photographic evidence of spirits although they appear similar to lens-flares or other photographic impurities. It was posited that these may be the spirits of future incarnations of people researching information online to events they did not attend.
