A car that has been lowered and scrapes the ground, spraying muck all over the place in rural areas. Usually has an exhaust so loud you have enough warning so you don't get covered in muck
'watch yourself, there's a muckspreader coming down the road, I can hear it'
When you scratch your balls then wipe your finger across someone’s lips while they’re not expecting it, making an audible “pop” noise when the lips come back together. This practice originated from Rez people.
Person 1-“Dude did you see that earlier?”
Person 2- “No what happened”
Person 1- “Junior Muck Mucked Cj in the hallway!”
