Mrs.Smith threw out my homework and said I didn't do my homework, what a brickass.
Mrs.Smith gave me detention because I didn't do her homework because my house was bombed by the Taliban, what a brickass.
People who's skull consists of pure concrete. They are either remarkedly stupid or stubborn.
"Jimmy just shoved a cactus up his ass, dude's a brickass"

Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
