A bet concerning one's private parts.
Bubba made a $20 wienie wagger(sic) that he could blowtorch his pubic hair off with a bottle of mapp gas before he went in to get his vasectomy hoping to avoid having to shave and to help pay for the procedure...little knowing that his friends would have paid for the entire cost of the operation to ensure he never bred.

Darryl commiserated on the hard and difficult life of a wienie wagger...just last night he went into a bar called the "Queen Bee" and flashed his johnson with tragic and traumatic results...how could he have known it was a rough trade gay bar?
