Fadoodlebop
A fadoodlebop is what you use when you're too lazy to think of a real name. It's also what you call something that doesn't have a name. Or it's a name for an island that's just a mess.
'That thing is a fadoodlebop. I'm too lazy to name it.'
'My island is a fadoodlebop. It's just a mess.'
'He called my dog a fadoodlebop. That's the worst name ever.'
