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.
