A portmanteau of the words "boost" and "nuke". It is the act of getting a boosted nuke in the Modern Warfare 2 video game.

To obtain a booke, one player enters a random Free-for-All match, and when there's an extra slot open, the other player joins in and they both go hide somewhere on the map. Once they find a good hiding place, they begin exchanging kills, with the help of tactical insertion, until one of them achieves a 25 killstreak (or 24 using hardline) which is of course a tactical nuke.
In this case, it's not an actual nuke but only a 'booke' because it was boosted and wasn't achieved by normal means.

The most important things boosters must have:

Equipment - Tactical Insertion (If they don't have this, then they're pretty fuckin' stupid)
Perk 1 - Scavenger
Perk 2 - Cold-Blooded
Perk 3 - Ninja
Death Streak - Copycat
Hey Jim, do you wanna get a booke with me? I want to see what it's like to get a tactical nuke, and if we activate it quickly they'll get so fucking mad!

Hey look at those idiots trying to get a booke. They must suck at CoD so badly that they can't even get a nuke without having to boost.

Old French root to the word "book"

Just as the french spell color as colour and theater as theatre, they were weird and spelled book as booke.

Plural: bookes
We like to go to the library and check out a booke

The phrase that defines streamer xQcOW's slot machine gambling addiction.
-*Mindlessly has xQcOW's stream on 3rd monitor*
-"BOOK BOOK BOOK!" suddenly screams through your headphones as xQcOW sees a second book appear in the slots, just before he is inevitably disappointed when a third book doesn't appear.
-*Ears ring from the tinnitus you now have*
