We operate in a world of jargon, a world of insider slang, a world of in-the-know lexicon. It's easy to get lost in the act of ranting in idiom, but do you ever feel like you don't know exactly what you're saying? Well, it's time to clarify those ambiguous bons mots of the Penn slanguage.

Tool:

1. One who lacks the mental capacity to know he is being used; someone who tries too hard; a poser. Can be seen wearing layered tight pastel colored polo's with all collars popped, drinking Mike's Hard Lemonade and listening to Jack Johnson.

2. Whartonite asshole; loves money and Management 100. Can't live without his BlackBerry; looks forward to slaving away this summer at his Goldman Sachs internship.

E.g. John is such a tool; he listens to Dashboard Confessional because Carson Daly told him to.

Biddy (alternate spelling bitty):

Used in reference to a group of hot girls; fantasized exaggeration of the girl(s) a guy plans on hooking up with in the near future.

E.g. Frat Bro: Yo, I'm gonna hit it with mad TriDelt biddies after our mixer.

Bit: Derivative of bitch/biddy; usually used by a female to describe her hot friends.

Fit:

Adjective; describes someone who is hot, fly and super sexy.

E.g. That girl you tapped last night was so fit; she looked like a mix of Rihanna and Beyoncé.

Morgue:

To sit inside and smoke weed all day; to do nothing but watch TV, etc.

E.g. I totally morgued out last night and ordered, like, $85 worth of Insomnia.

Custy (short form cust):

Refers to anything that is gross; also specifically references trashy bitches.

E.g: Ew, that stupid whore hitting on my boyfriend is wearing a fake rainbow Louis Vuitton purse. She is so damn custy.
