CF-ing 

CF-ing is that act of one fucking his or her cousin. It's most abundant in white trash familys. If they have offspring they tend to have mulitple limbs or have a slow process of thought. These people are known as CF's.

Y'all my cousin says I am the best CF in the family. She says I am a pro at CF-ing!
