jandu 

A not-so-common term used to describe a scrupulousnerd who trusts people, is very docile and more often than not, a loser. Can be preceded an adjective to more accurately describe a person. A jandu knows all the dirty tricks but as a principle, plays it straight.

My physicist friend John is such a jandu, his co-researchers unabashedly published his work without his name on the paper!

I'm amazed this 3d printer would produce useful prints with so many points of jankularity.

JANEURYSM 

An abnormal bulge or ballooning of your blood vessels which if untreated, can rupture. Janeurysm's are caused by prolonged exposure to political rantings delivered by elected officials of limited intelligence who have been unable and/or unwilling to maintain viability in a progressive society representative of current times. Frequently this defect is the direct result of inbreeding, rural living,involvement in organized religion, and home schooling. Janeurysm's were first discovered in a small population of people in Arizona in 2010; most often Democrats, Hispanics, Gays and Lesbians, college graduates, and anyone who has not suffered major head trauma or has been lobotomized. NIH directly attributes the steady increase of reported cases to the appointment of Jan Brewer as Arizona Governor, specifically her racist positions, hatred of minorities and the poor, her pro life, pro gun, anti gay policies, her uncanny resemblance to the Crypt Keeper, her chronic halitosis, flatulence (both anal and vaginal), bad grammar, inability to enunciate multi-syllabic words, and her incessant desire to become relevant on the national stage believing that anyone who has not ever fucked a farm animal is interested in anything she has to say.

After 15-minutes of listening to Mitch McConnell ramble on about Obamacare, I had to leave the room or risk a janeurysm.

Janguear 

To "hang out." This is really the English expression 'hang out,' but Nuyoricans have given it a spanish pronunciation, thereby creating a new Puerto Rican slang word.

"Oye, yo estoy aburrido, vamos a janguear."
"Yo, I'm bored, lets go hang out."
