Gadsden Geiser

When a guy inserts his penis into a vagina and pisses. While the female simultaneously urinates. Hence, causing a massive vaginal geiser of urine.

Man, can you believe that Sarah let my brother Allen give her a Gadsden Geiser. It was so messy, his bed looked like a swimming pool.

Butt Geiser Surpriser 

Also known as the BGS, this is a loving sexual act in which the giver urinates up the butt of the recipient.

BGS tournaments are also known to occur in some parts of the United States, though the rules of the tournament aren't well known.

I couldn't believe the sensation brought on to me after receiving my first BGS.

After years of BGSing, I have a permanent limp.
