I found a purple rock!
A crazy way to stop talking about something crazy. You yell, 'I found a purple rock!' to make everyone forget what they were arguing about, even if it was totally unfair.
'I found a purple rock!' my brother said when I told him he was bad at video games.
'I found a purple rock!' my dad said when I asked about his old job.
'I found a purple rock!' my friend said when I told him his pet snake was loud.
