Eating KFC is a delicious extravaganza. A mouth watering joy of essence itself. But the Kernel will take back what it’s due. One may eat of its tastiness now, but the one will suffer from severe fire poops that draw blood shortly after. And this is the KFC Blood Oath.
Hey Josh, you eat that delicious KFC yet?
Sure have man! I enjoyed every moment!
Yeah, I’m sure! You think the KFC Blood Oath will be repaid tonight, or tomorrow morning?
Oh tonight for sure!!

An oath between men, usually homoerotic in nature, that is traditionally "bound in cum" (i.e. said deal is sealed through the act of sexual intercourse between said men).
Well, I don't know what to say. Mark's been a buttplug for awhile now but if willing to give me a man oath that he can get us tickets to Peter Gabriel next weekend I'm willing to give him a chance.

The highest from of promise a man can make. If a man breaks a testicle oath, another person is allowed to punch him as hard as they can in the testicles. Testicle oaths must be used with caution, but they are a sure-fire way to know if another man is telling the truth.
Patrick : "Hey man did you eat my underwear?"
Josh : "No way of course I didn't."
Patrick : "Testicle Oath?"
Josh : "Testicle Oath."
Josh : "No way of course I didn't."
Patrick : "Testicle Oath?"
Josh : "Testicle Oath."
