What you're describing is the new popular and also wrong use of this great and useful and specific word which fills a legitimate lexical gap. I'm not hating on you. I'm just very passionate about this. Liminality is a great concept, great term, very useful. Turning it into "le creepy empty room with le slenderman" as is popularly becoming is very irritating to me because we already have words to more or less accurately describe that.
