Also known as Advanced Procrastination Literature or AP Lit. for short, is a high school class for "gifted" seniors who are supposedly extremely intelligent. In reality, these students have simply mastered the art of Bull-Shitting their way through English for the last 3-5 years of their lives. They just pull ideas out of their ass and write a fancily worded essay the night before and get A's on everything.
Giorgio: Oh my gosh Adam! How do you have an A in Advanced Placement Literature
Adam: It is actually called Ass Pulling Literature, I just wrote this essay that I got a 100% on last night
Vanessa: Me Too! These ideas came straight out of my asshole!
Having sexual intercourse. More specifically, 'pulling ass' means to pick up partners triumphantly or with ease, often after doing something attractive. To be smooth and have it lead to sex.
