look up any word, like the eiffel tower:
To smack a foe or loved one in the face with a strong open handed downward motion then quickly and without pause reverse the momentum of said smack into an equal or greater strength upward motion back hand to the opposite side of the face.
When I found the asshole that took my last beer I gave that motherfucker a round tripper.
