When a man ejaculates within a woman's cooch and proceeds to continue humping away even though she is filled with his population porridge. The rod/thrusting action is very similar to how the people (in the days of yore) churned butter.
The fact that spooge is white and creamy, similar to cream prior to it being churned into butter, just adds to the greatness of this term.
After busting a nut inside her, I was churning butter for about 4 minutes until I started going limp.
