fratter 

A fraternity bro who just can't quit fratting, even though he's now 42 years old, living off his second wife's social security income, and repulsive to all females.

An overgrown blustering fratter was in a store, mask at half-mast, nattering away via cell phone as he was being served.

Fratterall 

A drug utilized by fratdaddies and fratstars alike, so they may see a new, glorious sun rise across the fratcastle as they reminisce about brotastic night worth not remembering. Typically snorted, accompanied by 4Broko and/or sorostitutes in hand. Warning: may suddenly present with inability to feel/care about anything, including the slap to the face from the diamond-speckled pussy your slaying upon realizing you're not her boyfriend.

"Did you just sneeze blue?" - common question directed towards fratstars whilst lightning a couch on fire in the fratcastle's courtyard

"Fratterall has been scientifically proven to enhance the frattiness of the user. Fratlaps have unquestionably become more efficient, and the collective GPAs of Greeks has undoubtedly risen far beyond those of the GDI."
- Fratrick Ivey, M.D., Professor of Fratology

Fraternal Twins 

("fraternal"), meaning that each twin develops from two different eggs and each egg is fertilized by its own sperm cell. We can be passed as best friends even though we are fraternal twins. We are basically siblings but we are the same age so its different we share such a strong bond we hang out all the time.

Girl: Wait shes your twin? I thought you guys where best friends
Me:yeah shes my twin, we are fraternal twins we don't look alike.

boner in the frat 

A man who thinks he’s fuckin chill, but actually is a pussy fuck. Kids that think they "trap" but are actually those dudes drinking mikes hard and dancing to mainstream alternative music. Those dudes who consistently say things like “Squaa” or “Dank!”. In addition, any fuck that regularly talks about turning up or how he "got so fucked up" is a classic Boner in the Frat.

Drinking mikes hard=BITF
Drinking only beer=BITF
Ordering chocolate milk at a local food establishment=BITF
Duff=BITF

(1)Sarah: "He took 5 shots and hes already passed out in the bathtub"
Jim:"Wow, whata fuckin boner in the frat"

(2)Mike:"Damn, that dude just killed that entire handle and hes not even fucked up"
John:"That dude is no boner in the frat"
