look up any word, like donkey punch:
 
1.
A group of female friends that act nice to your face, but talk behind your back.
"Those girls at the barn are cuntchum, when I walk in the room they get silent."

"I walked past the cuntchum today and heard them talking smack on you."

"You are being cuntchummed by Nicole and Melissa, I wouldn't talk to them anymore."
