Dude, Mark got so shitfaced yesternight, I think he went home with that gay guy James.

Yesternight was the worst day of my life.

So, what happened yesternight, anyway?

Mike and Katie fucked yesternight.

Taylor: "The music video was due yesterday by noon; did you complete it in on time?"
Alex: "Yes, barely - I finished editing it yesternight."

or

Audrey: "When was your basketball game?"
Ella: "It was yesternight."

or

Miguel: "Did you see the movie yesternight."
Luke: "Of course, that was opening night."

“Do you remember when we went to bed YesterNight?”

Did uncle Jonny come over yesternight?
