Grade-B Jackassery 

Grade-B Jackassery is a common form of "Jackassery" on a grading-scale starting from "Grade-A Jackassery", but is specifically one level lower in intensity.

"Come on Mr. Bucknell, that form of Grade-B Jackassery is not appreciated here."

"You know I was being a Grade-A Jackass, but James you can't be following my Jackassery with Grade-B Jackassery. It's just not the same thing."

7th Grade Bi 

Used to describe someone who claims to be bisexual, but really isn't. Usually, these people tell others that they are bi, either because
A) they think that it's cool to be bi.
or
B) they can't deal with their inability to understand the opposite sex.

A: Hey, I heard that Jennifer said she was bi!
B: Naw dude, she's a 7th grade bisexual dude. She wouldn't do it with another girl.

Weapons Grade Bullshit

A patently absurd or ridiculous statement. Especially when made by a person in power or with enough status that he should know better.

Tony Blair: "Saddam has the capability to strike at UK troops in Cyprus with just 45 minutes warning".

Jim: "Man that limey fuck is talking some prime weapons grade bullshit"

G.W. Bush: "Iraq is a threat, they have weapons of mass destruction".

Aisling: "The only thing weapons grade is the bullshit that dude talks"
