Sinsual 

A cross between Sexual and Sinful resulting in a very erotic, hot combination of items which are usually videos, pictures or erotic stories.

Sinsual Daydreams with Kymber help me release my tension and sexual frustration after a long, hard day at work.

sissue 

A whiny "crybaby" complaint that makes the bellyacher look like a sissy.

A lot of the "Dear Abby" letters are so petty and asinine that they are nothing but sissues.
