[Shmayonaise] 

The thick creamy substance that explodes out of the head of the male organ, also called the penis, and into the mouth of another human species. It has the flavor of the great sandwich filling "mayonaise" or "Miracle Whip" which ever is prefered.

1. I could use some of that shmayonaise in my mouth or on my sandwich.

2. I would like a McChicken with lettuce, tomato, and Shmayonaise

shameonaise 

Ejaculated semen after solo masturbation. Named after the feelings of guilt and despair at current situation associated with the period occuring immediately after secretion.

FROM A DIARY:

As I scooped the shameonaise out of my belly button, I realised that the twenty four years of my life have been nothing but failure after abject failure.
