Uncle Matt is a slang term used to refer to someone who is involved in the illegal sale and purchase of marijuana and shoplifting. The phrase "the only thing down low for Uncle Matt" is used to describe the activities that he is involved in. It implies that he is involved in activities that are not socially acceptable and that he is trying to keep them hidden from the public. Shoplifting is a crime and the sale and purchase of marijuana is illegal in most places,
A floral store that once existed on Bald Hill Road in Warwick, Rhode Island in the 1980's and early 1990's. The place to go to pick up flowers for your cheap n' easy Warwick girlfriend that you just met in the Warwick or Rhode Island Malls, or for that cute girl at Ann & Hope. Actually had the best selection of plants I'd ever seen! I really miss that place!
