Maria-Pipeline 

The Maria pipeline is a pipeline or rabbit hole that Twitter and Tumbler users might enter after excessive usage of said platforms. In a bid to fit into the community the person in question will do a complete identity shift, sexuality shift and even (in extreme cases) gender shift. The Maria-Pipeline phenomenon is named after the Norwegian celebrity Maria, who is known for going through the pipeline and spreading awareness of it.

Ooh man, She/He really fell deep into the Maria-Pipeline, it's a completely different person now!
