chimney dick

Chimney dick refers to a male with very little (or no) ejaculate. This can be caused by excessive masturbation or sex. Scientists disagree on whether it is hereditary or not though smokers tend to be more prone to this condition... hence the double entendre.

You neeeed to quit smoking so we can have this baby... ain't nobody gettin pregnant when all you bringin is your chimney dick sputtering smoke stacks.
