What does it mean to have a large friable polyp? i have a family history of colon cancer and have to wait 2 weeks for the results.

A description: It is just a description by the gastroenterologoist (endoscopist) of how it looked to him/her. It does not mean it is cancer. You will to wait for the pathology report for a final diangosis as to what it exactly is.

Patience: Waiting for test results can be torcher. Usually it takes 3-4 days for the pathologist to prepare the speciman and then evaluate, although different labs can vary in their time. A larger polyp would be concerning but the friability of the polyp would not change the potential diagnosis.

Polyp: I am assuming you mean colon polyp. If this was biopsied at the time of colonoscopy it should only take 2-3 days to get results. The question will be whether it is benign, precancerous, or cancerous.
