What does Bitchy McBitch Pants mean?

Bitchy McBitch Pants meaning in Urban Dictionary

The man, Lenny, who was the cashier at Wendy's. He had been complaining, becoming a bitch, and sitting around performing nothing. Therefore I believed to him, "Hey, shithead! End becoming such a Bitchy McBitch Pants and I'll pay for my food! Only end fucking complaining.", yeah...I'm prohibited from that specific Wendy's now. At the very least i obtained my meals.
