To fool someone in thinking that what they thought of, said, or did was cool. Enticing them with a high five, than retracting said high five.

After said retraction of sarcastic high five with accompanying "PSYCH!" it is customary to say, "I just high five psyched you!"
twitard: Dude, I totally saw that new twilight movie! it was awesome!

Smart Guy V: Really? Cool! High five! (raises hand to initiate high five) ... PSYCH! Twilight sucks! I just high five psyched you!

When you slap a girls arse during a particularly heavy menstrual cycle and you return with a red hand in the fashion of the red hand that adorns the badge of the Ulster rugby team.
After getting an Ulster High Five I think I'll just masturbate instead.

Slapping someone and leaving your hand on their face for more than 1 second. Thus high fiving their face. If you remove your hand before 1 second has passed, you have slapped your friend and thus subjected yourself the a slap in return.
"Man you just slapped me!"
"No, I gave you a face-high-five. My hand stayed on your face for longer than 1 second."
