Jeff. I think I was so friendly to Bill last night that when he asked me to go into business with him I think I crossed the Chum Line.

Get the Chum Line mug.
When a person sharts while wearing a thong or g-string.
"She thought she was going to fart, but ended up chumming the line in front of the whole pool party."
