A sexual act when a man is flaccid and his girl comes up in between his legs from behind, placing his balls on her face, she blows very hard on the back of his penis causing it to fly up like an elephant's trunk. His taint creates a channel of air and causes a whistling sound when the girl blows.
I had such bad whiskey dick after the bars that I had to ask my girlfriend for an elephant whistle before I plowed her like the hog she is.

Dude, I just got out of the shower and was standing naked in my bathroom when out of nowhere my girl comes up behind me and gives me and elephant whistle.

I thought I heard someone torturing animals next door but it turns out it was just my roommate getting an elephant whistle.
