Four-balls

[Paul McFedries]

Thursday's Word Spy ("eco-porn") used the following citation by Molly Ivins:

"We're all used to eco-porn by now; those beautiful television ads featuring
some natural jewel, during which an announcer with a four-balls voice tells
us how much Exxon or some other gross polluter is doing to keep our precious
earth green."

I'm interested in knowing more about the adjective "four-balls." I assume
"four-balls voice" means a deep, masculine voice, so I'm guessing that
"four-balls" implies that it sounds as though the announcer is
doubly-endowed in the testicular area. True? Hints and eye-openers would be
most appreciated.

Here's what little I know so far:

Naval slang:
Four balls - Midnight, which in the military's 24-hour timekeeping system
may be written as "0000."

Epithet:
By the four balls of Jesus, Mary and Joseph

Lame joke:
Confucius say: Baseball is wrong; man with four balls cannot walk.

Pretty good joke:
A recent Scottish immigrant attends his first baseball game in his new
country and after a base hit he hears the fans roaring run....run! The next
batter connects heavily with the ball and the Scotsman stands up and roars
with the crowd in his thick accent: "R-r-run ya bahstard, r-run will ya!" A
third batter slams a hit and again the Scotsman, obviously pleased with his
knowledge of the game, screams "R-r-run ya bahstard, r-r-run will ya!" The
next batter held his swing at three and two and as the ump calls a walk the
Scotsman stands up yelling "R-r-run ya bahstard, r-r-run!" All the
surrounding fans giggle quietly and he sits down confused. A friendly fan,
sensing his embarassment whisper, "He doesn't have to run, he's got four
balls." After this explanation the Scotsman stands up in disbelief and
screams, "Walk with pr-r-ride man!"
