high doubt 

1. When there is a chance that the statement someone just made is completely false and full of shit.

2. A way to question alternative facts

Andrew: High doubt that a word of truth came out of her mouth, let alone his.

double high-five 

When you go for a traditional two handed high-five and once the opposite party's hands are high in the air, you punch 'em right in the zipper.
Coined by Johnny Knoxville on Conan.

"Don't go trusting ol' Jim over there, he'll trick you into a double high-five."
