A term used to describe a drinking style between chugging and sipping. When slipping your drink, you slowly let it flow down your throat without stopping to breathe.
Dude 1: "He brought some Jager and he's gonna slip it slow, like Mick Jagger"
Dude 2: "Mick Jagger drank like that?"
Dude 1: "How the hell am I supposed to know? It rhymes though so I said it..."
