An acronym for "nigga, this shit's wrackin' my brain."

When something of particularly vexing circumstances is met with an unsuspecting mind.
This should be used in a situation where one cannot come to a conclusion, such as discussing math, philosophy, religion, or anything else that's impossible to understand.
1) "How could God have created space if He wasn't a part of it?"
"...ntswmb."
2) "Calculate the volume of the solid over the square R = {(x,y)|-1<=x<=1,-1<=y<=1} bounded above by the graph of f(x,y)=8-x2-y2 and below by the xy-plane."
"...what? ntswmb."
3) "I'm pregnant!"

"But I pulled out!"

"Sorry!"

"ntswmb!"
