Gallubies
A dumb way to say something else when you can't think of the real word. It’s like saying 'gallubies' instead of 'dumbass' when you’re too lazy to use the right word.
'I don’t know why I ate that whole pizza. It was just a gallubies.'
‘He said something stupid, but I didn’t want to use the word ‘stupid’ so I said ‘gallubies.’’
‘She turned her phone off during my rant. That was the worst gallubies ever.’
