When someone who normally is not a bottom, does so for reasons of love.
I'm a top, but also a love bottom because I'm head over heels for him.
This phenomenon occurs when at least two people argue or discuss something intensively that they wouldn't even give a shit about if they weren't doing ... coke.
Please don't bother Natalie and David, they are literally having a coke-cophony in the kitchen and everyone has moved to another room.
