     When a man "blows his wad," at least two different things could have occurred: he either spent or lost all his money in a wager (his wad), or he spent or ejaculated his sperm (his wad). Thorne goes on to suggest that since at least the 1950s "blow," in this context, is a euphemism for "ejaculate."

2. (idiomatic) To expend all of one's resources or efforts; to express all the arguments or ideas which one has.
3. (idiomatic, vulgar) To ejaculate, to cum.
