Going out and drinking hard for many consecutive nights, such as one would do over a wedding weekend or Mardi Gras.
"Why are you going home, it's only midnight?"
"It's been five nights of smith for me, I'm tired."

"Exams are over, I'm going out for five nights of smith!"

"You look bad, it looks like you've had five nights of smith."
