prewee 

As a lad you will always prewee. The little burst of wee you let out before letting go of the full power to check if you have your aim right. Make sure you don't annoy the Mrs by not preweeing and making a mess!

Dave: Mate, I can't believe it, I've just pissed on my leg!

Steve: I've told you before, do a prewee and you'll be fine! No accidents!
