Gallubies
A stupid word you use when you're too lazy to say the right one. It's like trying to sound smart but ending up sounding like a retard.
‘I can't remember the word, so it's just a gallubies.’
‘He did something cool, but I called it a gallubies because I'm an idiot.’
‘She said something funny, but I said it was a gallubies because I'm too dumb to know the word.’
