When someone says something so outrageous and unbelievable, one may say "Are you out of your tree?" which means that the person is out of their mind on such an idea. The phrase originates from the popular Nintendo
game, Animal Crossing
Tanner: So what are you trying to do here?
Reil: I'm going to jump that shark tank
on this here bike.Tanner
: Oh no, no, no! Are you out of your tree?! You can't hope to jump something like that on that thing. You may as well start jumping turtles before doing something so unbelievable.
Reil: But I jumped the turtles last week...
To be crazy, to do something insane/crazy,
Like being out of your mind
Bob: I'm going to go jump off that bridge
Frank: You must be out of your tree!
