convisualisation = a combination of conversation and visualisation.
For instance asking a question (in a conversation) in order for the questioner to
get a indepth look (visualisation) on the person being question's state of mind or being, in a deeper, detailed more nosy matter than
just for instance "how are you?".
Or
just paying attention to the smaller details in whatever you're
talking bout.
So if you're asked, why do you want to know so much about a certain thing you simply respond "just makin' convisualisation".
