Yosemite or Yos for short can be used as a synonym for yes, yea, yeah, ye, ya, ye and many more by other's definition
If your friend asks if you are doing well one might reply "Yosemite or Yos" instead of yes or yeah.

Get the Yosemite mug.
A daring sexual act done by two or more rock climbers. As a male climber ascends a top-rope route, he secretly works himself toward climax. Upon reaching the top, the climber gets the belayer’s attention: making eye-contact the climber proceeds to ejaculate on the belayer’s face.

This act should only be attempted by experienced climbers, prepared to down-climb their route as a Yosemite Finish may result in them being abruptly taken off belay. (It is also highly frowned upon at indoor climbing facilities.)
Dude, I had to down-climb my route Saturday after I gave that girl a Yosemite Finish. She doesn’t want to go climbing with us anymore.

More badass than a regular squirrel, a Yosemite squirrel is the Alex Honnold of the squirrel kingdom. It climbs mountains, drinks beer, and snatches food out of unsuspecting hands.
(Squirrel on top of half dome snatching lunches)
Adrian: How did that squirrel get up here?
Me: it’s a Yosemite squirrel. It does what it wants.

A genderbended version of Yosemite Sam.

Samantha: HE IS NOT MY BROTHER!

Samantha: I'm a genderbend of this guy. My name is Yosemite Samantha. AM I CLEAR?!
