The process of curbing all other responsibilites in favor of playing a marathon session of Call Of Duty: Black Ops. This is sometimes unintentional, as the player becomes so involved in the game, he or she essentially "blacks out" and doesn't remember anything not COD-related.
Matt was playing Call of Duty so long that he had a Black Ops-out and forget his anniversary. Fortunately, his girlfriend also had a Black Ops-out.

When committing a crime the individual partaking in it would prefer to be dressed in all black, witch makes sense at night seeing it is easier to blend in all black at night however being all blacked out in the daytime is suspicious and ironically draws more attention to person. To combat this a person who commits crimes should where neutral colours during the day, preferably grey to blend in and not seem dodgy however at sunset it would be in your best interest to wear all black. Therefore the phrase "greyed out in the day blacked out at night" came to be.
Person 1:I like being blacked out at all time fuck wearing other colours
Person 2:Bro, that will draw more attention to yourself. greyed out in the day blacked out at night. Not as bangers.
Person 1: Fair enough
