loud challenge 

A YouTube stunt usually pulled off by urban African American youth, in which the person doing the challenge lights up weed (usually a blunt) in a public place i.e Walmart, subway, McDonalds etc. This is a risky challenge as to the obvious problem of possibly being caught or even arrested.

Person 1: nigga I gotta blunt but we in Walmart
Person 2 with camera: loud challenge bitch
