Don't piss on my leg and tell me it's raining. 

Don't hurt me and then pretend like you had nothing to do with it.

You argued, privately, to each member of the committee that I should be fired and now you come by on my last day to tell me how sorry you are about what "happened." Don't piss on my leg and tell me it's raining.

piss on my chips and tell me it's vinegar. 

This is a 'mangled metaphor'. It mixes up 3 idioms:

Piss on my leg and tell me it's raining
Piss on one's chips
Piss and vinegar

To deliberately and painstakingly go out of one's way to ruin a friend's chances of success. Usually done jokingly with reference to the opposite sex.

No way do I want you as my wingman. You would piss on my chips and tell me it's vinegar.

piss on my leg, and tell me it's raining

Disbelieving response to an attempt to mislead, equivalent to: "pull the wool over my eyes"

You tell me that you've worked as an airline pilot and a surgeon, too? Go on ... you'd piss on my leg, and tell me it's raining.

A word that has simply lost all meaning throughout history. It’s definition has faded into obscurity after being trending on Urban Dictionary for almost two years. 

A sentence in the definition of "Watermelon Sugar" that was colored blue because of the three other words called "A word that has simply lost all meaning throughout history. It’s definition has", "faded into obscurity after being" and "trending on Urban Dictionary for almost two years." which makes the said sentence a link which makes it blue.
(There is a feature in Urban Dictionary where if a word has no links in the definition, then it would automatically generate the links)
