Matching is a friend throwing down some weed if you throw down the same amount too. Like, if your about to smoke with a friend and they say, "Wanna match?" then if you pack the first bowl with your bud, they'll pack the second with theirs.
yup yup.. or if you don't have enough to roll a good joint I've asked someone to "match me" with the same amount that I threw in so I can...
