haha - thats a funny way to put it. Well creatine by itself doesnt really have the macros or calories to be considered a meal. If you mix it with your whey protein (which should also come post workout) then you COULD count it as a meal but it really depends.
For me, when I'm cutting (like right now) I count my protein shakes as a meal, usually mix them with water and nothing else.
When I go back to bulking (which will be in about 8 more weeks - hooray!), I mix the shake with milk, berries, maybe some oats and usually have a solid meal on top of that.
