Another term for hanging out, or not doing much of anything. Most often, the activity of slushin' is performed during the summer, while drinking a slush of the watermelon, blue raspberry, or lemon-lime variety. This word was created during the summer of 2007 by Stefanie and Devin at Papoose Pond.
Stef: "Omg, we really need to find our friends."
Dev: "I know, I don't feel like slushin' around all day."
