Hardcore dip. Usually placed in the left corner of the mouth, bottom lip, to stimulate the maximum taste. Mostly, us southerners use this when the wives are bitchin' or some stupid shit to take off the edge. On some occasions, it can be placed on the tip of the penis and used as a lubricant. If the bitch gives you head while chaw is on the dick, it is known as a Georgia Cotton box.
"Man I need a good chaw"
"i hear ya, I've been busy as fuck all week"
