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!”

Blue Molly 

Blue Molly is Blue MDEA (Blue 3,4-MethyleneDioxyEthylAmphetamine). It's part of the MDxx family of chemicals. It's made by reductive amination of MDP2P (3,4-MethyleneDioxyPhenyl-2-Propanone) with ethylamine using a non-toxic Aluminum Galinstan amalgam. The dose range is 100mg to 200mg. Blue MDEA makes you dance to music, love people, share secrets, and is sedating and relaxing. The sedating part is what's responsible for rumors of heroin laced ecstasy. So sometimes people take some Blue Speed along with the Blue Molly. Sometimes Blue Molly is Blue MDMA.

Fernando: I tried 120mg of MDEA and I was rolling. This Blue Molly is great!

molka 

Molka is the name of somebody really unique and very rare. We do not find Molkas at each corner of the sreets, it is like Pokemon GO, when you find a Pokemon you've been searching for ever, you've liked this metaphor, huh ? So, if you ever find a Molka, do not waste your time, ask her for a selfie, you should be very pleased and lucky if you ever have the chance to find a Molka. The whole point here is not only here to glorify the name Molka, it is also to remind you, you reader that is lost on the Internet searching random definitions on Urban Dictionary, to remember you that every person on the Earth is unique and we should treat every person as so.
-XO.

I love her because she is very Molka, unique in her kind.

Moldy Shorts 

Fan slang for Voldemort, from the Harry Potter series.

The second war with Voldemort would have gone much easier if the light side had just called him Moldy Shorts.
