TV Pregaming 

To watch the season finale of a show immediately before watching the premier episode of the next season of the same show.

"I'll be watching the new How I Met Your Mother at 8, but I'm watching last season's finale before that."

"So you're TV Pregaming?"

"You know it, brother."

preaching to the choir

Preaching to the choir means you are trying to make believers out of people who already believe, or convince people who are already convinced.

"We could start a new tradition, Birthdays without Boyfriends. It could work."
"Preachin' to the choir here baby."
