cheese puffing or cheese puffed, is when someone is either super tired, or "cashed out" from the night before, mostly from drinking, or possibly doing drugs! kind of like a hangover
me: yo look at that dude, he is totally cheese puffing
friend: no kidding, he must of had a rough night!
friend#2: I was cheese puffed a couple morning's ago, not the greatest feeling! ,
