I was on youtube the other day and passing the arrow over the thumbnails when on a vid about alien covenant there was a clip of some people wallowing in mess. Its not from the film and it looks so familiar but I cant remember. Anyone know where this clip is from? Its at approx7:38. Only short

I think it's "not another teen movie" or something similar. And I believe it's shit they're wallowing in

Yeah it's from, Not Another Teen Movie. The floor in the bathroom breaks and they fall through. That's the end result.
