Also known as Captain Morgan 100 Proof. Named for it's propensity to cause those who drink it to lose all recollection of what they did the previous night.

Friends who often drink so much every time that go out that they do not remember the night's activities. These friends consequently have a solid relationship built off of forgotten yet (hopefully) spectacular memories.
Kellie and Rebecca aren't just best friends, they are blackout besties, they rely on everyone else to remember their nights but this makes their friendship even stronger.

after pulling an all-nighter, not being able to remember anything that happens until noon the next day, losing all control of motor skills, drooling all over your notes in class...at least until noon, and being convinced that "Wolfpack, are organized" is a complete sentence
Guy: Look at these notes I took in my 8:30 class.
Anne: Wow...they're pretty...interesting. If I can directly quote from your notes: 'Wolfpack, are organized."
Guy: Don't hate. I was blackout tired.
