A homoerotic group of males that stand around a keg, talking about how drunk they were the night before. In between cat calls and passing out they like to fight and jerk each other off.
A: "Hey man, you going to that fraternity party tonight."

B: "Are you kidding? I'd rather watch Sex in the City, naked with a snapple bottle jammed up my ass."

A: "Yeah, fuck those fraternity fags."

From a scientific stand point, the mentality of frat is extraordinarily close to that of a street gang as they both have various symbols and signs that you find engraved into bathroom walls and desks. They believe that strength comes in numbers and the individual is powerless by themselves. If understood by its definition, then a fraternity is a group of individuals who’s self esteem comes only from the amount of friends they can initiate into their frat. There is the social experiment of placing a member of a prestigious fraternity into a setting of those who are not part of the frat lifestyle and after a small amount of time, that individual conforms to the interests and beliefs of that group. Thus the strength of their fraternity is disproved. This is exactly the reason fraternities do not allow those of low income levels to enter their social groups. From an evolutionary stand point, diversity is beneficial in all forms. Thus a fraternity who lacks unconditional acceptance is flawed in its abilities.
the young man joined the fraternity for social acceptance but found unwarrented rivalries and economic discrimination.

A social group made up of men that actually do a lot of community service and gain a lot of connections for life. While some are expensive, you can talk to them to see if they can create a payment plan for you. These are often confused with unrecognized gangs that call themselves fraternities. Real fraternities don't rape women.

organization that exists to sell t-shirts
frat boys must have at least 20 shirts from their fraternity in their closet.

t-shirts are made about anything they do, inc road trips, campings, parties, dinners, and even the official (insert greek letters) 'taking a group dump' t-shirts

A group of fucking douchebags that think they are better than anyone that is not a part of their fraternity and are the kings of hazing kids to death and treat girls like shit because they have absolutely no respect for humankind. Boys have to pay to go to their parties or they even get told to fuck off by the cool ass frat brothers, girls get in for free. They changed for the worst, they potentially were good people in high school.
Christian: hey man how’s the frat you rat?
Cool frat boy: don’t call a fraternity a frat. Do you call yourself Chris?
Christian: actually I’m cool with that, it can be short big man, who says I can’t call a fraternity a frat? Looks like you hate the world because most people just say “frat”, but god forbid you and your brothers will get butthurt by it being called “frat”. Wow you use to be one of my good friends since pre-k and now your in a frat. Wow what a change dude. Enjoy your frat you douchefuck.

Twins that do not look alike.
Most people think of identical twins when you say twins, but twins are just people that are born on the same day (as you should know if you are over 6).

Because of that, fraternal twins do look a little like, but not enough to be considered twins. Often it is assumed that they are siblings of different ages or cousins.
"This is Jane Doe, she's my-"
"Sister?"
"Yeah...But she's also my twin."
"Oh really. Yeah, that's why you look different." *snorts and walks away*
(Joann and Jane Doe at the same time) "Bye, ignorant human being who acts like they are six!"
Mary-Kate and Ashely are idiots...And they are also NOT fraternal. At least not naturally.
