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.

seshmonster 

A person who is particularly partial to the Sesh. Generally found in odd numbers as the voice of reason needs to be overruled when pondering whether to continue the sesh or return to normal life. Sehmonsters often refer to a prolonged Sesh of 3 days or more as "holidays" and can be observed trying to persuade non-Seshmonsters to join in on these "holidays", often resulting in loss of employment.

"That lad is a wild seshmonster"
