look up any word, like ratchet:
A normal bed pillow place behind a females head while the male is in the dominant postion (sitting on her chest) during oral sex. Then grabbing the pillow's four corners with both hands one can use the head hammock to work the females head during oral negotiaions.
Sweatheart was tired of me pulling on her ears during oral so I placed her head in the head hammock and let'er rip.

It's a Hammock for Heads and.... a Hammock for Head!!!
