The afterproduct of cleansing one's anal region with a leaf (typically from a poison ivy plant).
Example 1:
"Bro, I forgot to pack toilet paper for the camping trip!"
"I guess you'll have to make a Brazilian Falafel."
Example 2:
Duncan was running for Cross Country when he needed to poop, he quickly made his way into the bushes and pooped, he wiped with a poison ivy leaf, and left the Brazilian Falafel, and he experienced a sensation of intense painful ticking.
