Molly Piss 

British slang, originating in Plymouth, Devon, it means an ineffectual male. The epithet also implies that the recipient is also moronic impotent, effeminate and incompetent. The origin is believed to derive from the expression 'not worth a Molly's piss', where Molly or Mollie was a slang name for a prostitute. So a Molly Piss is someone who is not worth a prostitute’s piss, meaning that they are of no account or totally worthless.

“Mark’s all uptight and emotional because Terry pointed out a fundamental error in his figures, says he’s going to resign because he can’t take the constant criticism.”
“What a molly piss!”
