What is a "spray cheese" and why are people on my timeline talking about it?

@vaporeon_ Imagine a spray can. You press the lid. What comes out? That's right, buddy: It's cheese

@amy How do you spray a cheese? Any cheese that I've seen is solid, either in flat rectangles or shredded, but it's too solid to spray it from a spray can...

@vaporeon_ @amy do they have whipped cream from a can in Germany?

@wallhackio @amy Yes, but that's not cheese!

@vaporeon_ @amy it's just like that but it's (artificial) cheese
