When a man's boxers or briefs ride up into his scrotum, causing extreme discomfort.
The reason my nutsack is so sweaty is because I've had a ball wedgie for the last hour!

When a mans dick and balls get somewhat tangled between his legs, either by walking, sitting, or sleeping.
When I wear shorts with no underwear and try to sit down, my cock and balls sometimes get cought under my thigh causing a ballwedgie.
