Poo Stalling 

Being a very revolutionary concept, Poo Stalling is when one holds in their poo for the sole purpose pooping later when an undesirable event comes up that the poo-carrier would rather not attend. Poo Stalling causes every attendee to wait on the individual who chooses to poo at the time of the event, causing them to be anxious, mad, or even outright anal (if you will). Fortunately, pooping is a practice that can deter any suspicion as to why the one Poo Stalling showed up late, or didn't show up at all. Poo Stalling is a valuable and strategic art. It can be the final solution when circumstances seem daunting. Poo Stalling can even save lives.

Hilary had to attend a lame forum but luckily by Poo Stalling she was able to miss half the lecture and avoid any overly-concerning questions by her peers.

AP Stacking 

The process of taking as many AP courses as possible to increase your weighted GPA and look better for colleges. Tends to be done in the 11th grade, or Junior year.

The rigor of taking even more than 2 AP courses forces one to develop proper time management skills, as they’ll have extracurriculars and a social life to juggle.

Guy 1: Yeah, I’m taking 7 APs Junior year. Gonna be absolute hell, but I need that 4.8.

Guy 2: Wow, and I thought I was AP stacking. I’m taking 4, and self-studying for 1.

Guy 3: I’m taking two, but they relate to my major so it should be fine.

Guy 4: You guys are taking APs?
