Sexmonster 

A horrible creature derived from a series of both male and female human reproductive organs. The main body consists of a large gaping vagina (which may or may not be soggy) surrounded in a large fleshy sack. Sexmonsters have uncannilly large arms. Two immense penises sprout from it's head and one drags between it's stubby yet muscular legs. The penises can become erect or flacid depending on it's mood. It feasts primarilly on babies doused in it's own semen (used for easier digestion).

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"
