Here is a clean, genuine toast that takes about 45 seconds to read at a relaxed pace.

"For those who don't know me, I’m [Your Name], [Sister's Name]’s [brother/sister]. 

Anyone who knows my sister knows she doesn't do anything halfway—especially rock climbing. So it really wasn’t a surprise to any of us that she ended up finding the love of her life at the climbing gym. 

Now, I could stand up here and make a bunch of cheesy metaphors about them 'reaching new heights' or Elliot being her 'rock,' but I promised myself I wouldn’t do that to you guys. 

Instead, I’ll just say that in climbing, your partner is the person you trust with your life. You need someone who communicates, who pays attention, and who has your back when things get tough. 

Elliot, from the moment you came into the picture, it was obvious you were that person for her. You calm her down, you build her up, and I’ve never seen my sister happier. Welcome to the family. 

Everyone, please raise your glasses to [Sister's Name] and Elliot."
