Reverse Quack

• The act of running your nose up your partners butt crack while they dry hump a well downed pillow
• The act of holding a recently deceased goose by the neck, creating a seal with your mouth over their beak, and blowing hard enough to push their stomach contents out of their rear end to facilitate the butchering process

"He really gave her the reverse quack?" "Yea, funny enough she works at the slaughter house a reverse quacked a bunch of geese earlier!"
