Uncle Roach is mad rad. He is the coolest uncle around and you are very lucky if you have an Uncle Roach. Uncle Roachs tend to have "young bitches" and will have the craziest stories from his youth, however a true Uncle Roach doesn't let age get the best of him and will still be as wild as he was in high school.
when one takes a roach and sticks it in a bong and then proceeds to put bud all around the roach like a moat. Smoking the roach then lights up the surrounding bud when it gets to the bottom.
