look up any word, like bukkake:
 
1.
When banging a girl doggystyle you grab her by the wrists and pull both arms back towards you. Thus causing her to nosedive into the bed/couch/floor. The moaning and heavy breathing causes a vacuum effect upon any surface her face comes in contact with. This move is not for the faint of heart but one that can yield spectacular results. In other words, it's a game changer.
This girl I date loves when I go caveman on her and put her in "the vacuum".
