Used to describe a sex
act that some people find very disturbing
Both the man and the woman start out naked. The woman allows the man to put ~1 pint of whipping cream
into her anus
. The man then wraps a doritos
bag around his penis and uses it as a condom
The man then proceeds to fuck
the woman anally
while wearing the doritos
as protection. This continues until the whipping cream
has been churned into butter.
The butter can then be put on toast or used in another sexual act.
Joe didn't need lube. He and Sara did a canadian butter churn and the butter was enough to keep 'em from chafing.
They used the rest of the butter on their toast.
