The South Bend toothbrush is the act of waking up in the morning after a long night of drinking alcohol and immediately smoking marijuana followed by a cigarette or five. If the timing is right, beer, bourbon and vodka may be involved in this practice. This act is derived from South Bend, Indiana.
Casey: "Dude, I got way fucked up last night. Do you want to go down in the basement and hit a few bingers?"

Brian: "For sure. The good old South Bend toothbrush?"

Casey: "Hell yeah! Do you have any smokes?"
