The inability to form new memories once a certain amount of alcohol is consumed. I've never had a total blackout, more of a brown out, where I could remember if I thought about it or had assistance. And man is it nice to not have to worry about that anymore!!!
Not a stupid question, btw. It is good to educate yourself and see the scary things that alcohol can do.
