The sound of someone's voice when attempting to speak with a cock in their mouth. Also the act of muffling through the placement of a cock in a mouth
Example 1:
"Jillian, you better shut your cock hole before I have to cock muffle you"

Example 2:
Look at the camera and say "hi mommy"... (in a cock muffled voice) "hiiii mommy"
