Means to be thoroughly rocked via cock. Can be split up into cock rockery, or just plain cock rocked.
That game is pure cockery, it's insanely delicious.
Dude you just got cock rocked by a paraplegic!
During egg production, the male chickens are ground up and used as feed. A cockery is a mythical place you tell children that roosters go after when they are "discarded."
I felt a great disturbance in the cockery, as if millions of roosters suddenly crowed out and were suddenly silenced. I fear something terrible has happened.
