a method of making a woman water tight with only one man. Performed by placing one's penis in the woman's mouth, one and in her vagina and the other in her anus. When viewed from the side, the male looks like a praying mantis, hence the name.
She wanted to get water tight, but I don't want other guys around, so I did an Angry mantis.
