This is a saying used when someone says or does something extremely stupid or obvious. It came from the show "Workaholics". When someone does or says something as above, the person who says "that's a chop" is allowed to karate chop the back of their necks. The harshness of said chop depends on the action or words of the receiver. It comes in many forms.
Family pack - everyone in the room is allowed to chop the receiver
Hardies - hard chop
Softies - soft chop (when it wasn't too stupid or obvious)
Selfie - receivers chips themself
