Holding onto your penis during an earthquake of a magnitude of 7.1 or greater, and riding out the earthquake in guilt free pleasure; letting nature take it's course.

When you're having vaginal intercourse with a woman, you insert your testicles into her rectum. When you're ready to blow your load, you pull out both your genitals and put your balls into the woman's mouth to suck on, while you finish jerking yourself off only to finish on her forehead/hair.
Jessica doesn't like Gary anymore. I hear he gave her the ol' Double Quaker Shaker last night. What a legend.

Similar to the Thug Shaker, the Quaker Shaker defines when a historically Protestant Christian shakes their fat juicy ass on display for all to see.
