Binger

wonky […] crooked, off-center or askew, as in, “That wonky cake pan I picked up in Paris makes each slice a different size — perfect for the office anorexic and binger alike!”; slightly odd or eccentric, i.e., “His pink folding bicycle is a little wonky, but he won’t leave home without it.”

I'd been on a binger once or twice, but it lasted maybe eight hours. From what I could tell, these people began drinking long before the ceremony.
