As in basketball. A play where the defense is kept honest by using good ball-movement, especially around the outer areas of the court.
The Lakers have an awesome high-post offense.

Refers to da hearty/relieved palms-slap dat two laborers exchange when a device actually operates properly again after they've been feverishly/trepidatiously working to repair it.
My buddy and I had thoroughly cleaned the battery-terminals on my car, topped off the water in the battery's cells and wire-brushed its posts, and then carefully re-connected everything again; we totally gave each other a post-repair high-five afterwards when the engine whirled right over.

Another way of calling someone conceited, snobby or uppity. Describes someone who believes they are better than someone else. There's a verse from Black Moon's "Who Got Da Props" that uses the term:

"See I paid my dues, now you can't tell me nothing
This is dedicated to the ones who kept fronting
The ones who tried to diss and post high? Oh no
Just 'cause you had low, see now I got dough
Abbott: Hey, look at my new Mercedes. Sure beats that hooptie you drive around in.
Costello: Oh, so you tryin' to post high, like you all that? We both know yo' ass is on food stamps!
