Jacobian 

1. A mathematical transform involving partial derivatives in college vector calculus courses.

2. The mortal enemies of the BasILL face that have alliances to Reimann Sums and Laplace Transforms. Syn: Porcelli.

3. Any person, thing, or situation that stops at nothing to slow you down, mess you up, or give you (or any BasILL) random unexpected grief.

"Yo man that 416 forecast was total Jacobian"

OR

"Haha how'd you do on that Math230 exam?"

Jacobian Slip

A Jacobian Slip occurs when one mishears a word or phrase and questions the misheard phrase, thus revealing something about their internal thoughts.

Like how a Freudian slip can reveal internal thoughts, but with mishearing rather than mis-speaking.

A: Yo get me two large fries and a shake after you get gas
B: You want two large guys shakin’ their ass?
A: What the fuck
B: My bad, that was a Jacobian slip

Jacobins 

The Jacobin Club was the most famous political club of the French Revolution. So called from the Dominican convent, where they originally met, in the Rue St. Jacques, Paris. At that time, the term was popularly applied to all supporters of revolutionary opinions. In contemporary France it refers to the concept of a centralized Republic, with power concentrated in the national government, at the expense of local or regional governments.

The Jacobins sure were a rowdy bunch, always wanting to have a revolution and FUCK WOMEN.
