The wierd substance
That comes out of your belly button when you meet 'the one'
It looks like blood, bogeys and urine all mixed together and it is very thick
Once people settle down in their lives after finding 'the one' they donate their Spagoo to a special group of people who use it to make Jelly!
This is then eventually eaten by humans!
Vicar - You may now kiss the bride!
Now what are you going to do with your spagoo?
Groom and Bride - donate it!
