Vince Bobaganoosh is the best name for prank calling people. If someone asks you to spell it, abort the call immediately.
Caller: Hello, this is Vince Bobaganoosh.
Callee: Who the bloody hell is that?
Caller: YOUR MAMA!
(everyone around the caller goes "OOOOOHHHHH" until they realize the caller is an idiot and kill him)
Pajama casual is a term used when working from home and preparing for a video conference. All business above the waist and your pajama pants down below.
