The sexual act of sucking a man's penis with a mouth full of spitting tobacco, commonly referenced as "dip".
The term penned by popular Youtuber McNasty as a joke towards his friend Dallas, known online as Soup, in a video titled, "Warzone: TRY NOT TO WHEEZE"
Damn Bobby, I tell you what, Jimmy from down the creek brought this chick over to his house, and she gave him a Sloppy Dallas! She brought her own dip too!
