when you convince someone that they've done something or gone somewhere (like the grand canyon) by fabricating a memory of it by telling them things you've done that you've told them about before
an example of grand canyoning:

person 1: dude do you remember when we went on a trip to florida?
person 2: no i've never been to florida
p1: remember? the lady at that gas station said they didn't know what our state was (happened to p1, but not p2)
p2: oh yeahhhhhh!! i remember that now (was told that story by p1 years ago)
p1: see, we went to florida
p2: yea i remember

It is the condom women wear when they do not want to get pregnant. Similar to a male condom.
It is also something a male wear when they perform anal and do not want a frosted asshole.
Ex 1.
Girl: Baby please I'm tired...
Guy: Put that canyon condom back on, I'm going in.
Ex 2.
Guy 1: Are you ready yet? ;)
Guy 2: Not without a canyon condom on.

It's a verb.. Wgen a man goes " Canyon of Boise" then that is a person who is being super chill. It means to really be a lay-low kinda man. Mysterious. Or being massively under cover.

"Hey, whatever happened to that guy Josh? I haven't seen him around much?"

"I heard he's working for like the FBI or CIA or something."

"Yeah, I knew he was going out if state but I had no idea he'd be like all Canyon of Boise on us and just disappear like that."
"Hey bro.., why you hiding your Fake book profile?"

"Hey, I gotta disappear for a while so I'm going all Canyon of Boise for awhile."

Nobody knows where it is, nobody wants to know.. It's like the nowhere's ville of noplace land.
