Octaive
Octaive is when you wave your hand like you're cutting their head off and say 'eee' to make them feel like they just lost a bet they didn’t even know they made.
My neighbor octaived me when I told him his lawn is a disgrace.
My dad octaived me when I said he’s the worst dad ever.
My crush octaived me when I said I like his dog more than him.
