The same as shakin' in my boots, which means scared. The phrase is used sarcastically often.
The specific term comes from Austin Powers in which Dr. Evil says "I'm shaking in my little space boots", although some falsely attribute it to Toy Story. Also, the "little" is commonly skipped from the phrase.
Thug: "We comin to get chuuuuu"
Girl: "Oh mann i'm shaking in my space boots"

Verb: To pop bang. Similar to fuck shit up, beat some ass, create a commotion, or (not as common) to kill someone. The phrase possibly refers to the banging noise made when you pop a cap, aka fire a gun; however, the exact origin is unknown. Usually considered a ghetto term or part of ebonics.
I'm so pissed that I'MMA POP BANG!!!!!!!!!
