Sharp’s Lexicon 

To argue in favour of an opinion in a ridiculous manor to the point where the opposition can’t even argue back because your argument was so retarded. This also includes use of logical loopholes.

David-“Thomas used Sharp’s Lexicon the other day when arguing if you could float on water covered in oil.”

Sam-“What a retard”

UrbanDictionary's SHARE THIS 

The worst implementation of a SHARE feature.
It can be found under every single definition for the word BUT it only shares the top definition!!
Obviously if there are multiple definitions in a close race for the top spot you may like one of the other definitions but no matter which SHARE THIS link you click it shares the 'winning' definition.

UrbanDictionary's SHARE THIS option is the Epic Fail of Social Networking Sharing known to mankind!

the devil's sharpie 

Sometimes when I wipe... I'll wipe and I'll wipe and I'll wipe... a hundred times. Still Poop, still poop. It's like I'm wiping a marker or something. That's the devil's sharpie.

I think I just used a whole roll of toilet paper thanks to the devil's sharpie.
