The Undertaker 

When you throw your partner off Hell in a Cell, and they plummet 16 feet through an announcer's table.

"I gave my GF a sexy The Undertaker last night."
"Is she okay?"

Undertale is a game created by indie developer, Toby Fox. In it, you can choose to either spare every entity that appears before you, or slaughter them mercilessly. It has multiple endings, a fantastic soundtrack, and although it doesn't have the best graphics, its story, wittiness, and humor make it a very enjoyable game.

Undertale gave me big feels.
