When the writer of a book or a movie director makes a cliffhanger. The writer or director is then cliffing the movie or book.
Dude the writer is cliffing this book. I find these cliffhangers so annoying.
A "clif gookinator" is when somebody eats a cheese burger while having his/her finger inserted in another persons ass.
Me and the bros pulled a clif gookinator last night.
