An sexual occurrence in which, while in the midst of taking a girl from behind, one involuntarily rejects the contents of their stomach all over the girl's back. This sudden regurgitation creates a small haze of steam as it cools and covers her back.
I had 12 shots of whiskey, 2 four lokos, and a bud light before we did it doggy style and projectile vomited all over that bitch's back. It was the best Lithuanian Steam Blanket I've ever given.
