look up any word:
1. Crossing it up, Catholic Style
A handshake in the motion of the Catholic cross. It starts out as a normal handshake, then the hand position is changed so just the fingers are connected. From that point, the movement is up, down, then left to right and vice versa. The left to right movements should be done to the direction of the coolest person taking part in the shake. After the shake is done, it is optional for one to say "Cross it up," and the other to finish it by adding on "Catholic Style"
Person one: Oh look, Johnny and Tony are crossing it up, catholic style!
Person two: Yeah, they really must love Catholicism!!
Person three: STFU you idiots, catholics suck
