seamonster 

1. Form of sexual deviancy in which one of the male gender encounters an attractive female on the street during a rainy night, throws her down in a puddle, and rapes her. This is generally frowned upon by anyone residing north of the mason-dixon line. Elsewhere, however, not so much.
2. My dick

1. I was walking home from work the other night when I seamonstered this chick. She totally wanted it.
2. When she caught up with me afterward, she butchered my seamonster. Go figure.
