A sexual, misandrist action that takes place when kissing. While kissing, the girl sticks her tongue into the boy's mouth, pushing his tongue back towards his throat causing the boy to choke on his own tongue.
The unusual name is derived from Alice in Wonderland. (The crazy girl is following the rabbit down the hole.)
Michael: Dude, how was your night?
John: Dude that girl I was dancing with was finding the rabbit, so I punched her in the throat and sent her home.
