bellywhacker 

The act of diving/jumping into a pool, only to painfully hit the water stomach-first, often creating a loud crack noise and an even bigger splash. Somehow, every person present will notice if you do one.

"Ooh! That bellywhacker had to hurt!"

A phrase coined by Colin Lane in an episode of 'The Adventures of Lano and Woodley'. Used to describe the biggest bellywhacker imaginable.

"Oooh! It is the MESSIAH of bellywhackers!"

Tellywhacker 

Tellywhacker is any long 'stick-like' object that my 2 year old child (Telly) manages to grab and then use to hit anything, or anyone, within reach.

Look out! Chantel (Telly) has a Tellywhacker.
