It's what a Flerken does. (The Flerken are alien creatures resembling cats, from the Marvel comic book universe. They are interially higher-dimensional; and have multiple interior tentacles, some with mouth parts and others with octopus-like suction cups.)
It reaches out, grabs you with its interior tentacles, then engulfs and consumes you. That whole process is flerking, and you would say you've been flerked.
Note that it *is* possible for them to simple engulf and store you in an interior pocket dimensional bubble and later regurgitate you, living and intact.
In the Captain Marvel movie, Goose (whom Captain Marvel thinks is a cat) flerked the Tesseract, only to later cough it up on Nick Fury's desk.

"Hey Brian, look at my fat ass move!"
"Can you quit Flerking that small butt!!"
