Galdinore - Somebody who uses a dumb nickname that everyone laughs at be

Somebody who uses a dumb nickname that everyone laughs at because it’s so weird and just plain stupid.

My name is Sir SqueakyToaster. I toast bread for fun.

I go by Princess PuddingBiscuit. I eat pudding and biscuits for breakfast.

I’m called The Magnificent SockMaster. I have a sock collection.
