Okay I only know about wrestling as it pertains to WWE, so let's hope Bob wasn't thinking of UFC or New Japan or something.
Pin - You pin your opponent to the count of three to win a normal WWE match.
Ring - Wrestling matches take place in a ring. I think these two are gimmes.
Square - WWE rings (and most other promotions IIRC) are square. Pretty confident about this one.
Swing - You might swing your opponent in a match?
Force - Well, you can describe wrestling as a contest of forces...
These next ones are just random guesses:
Death - Even pro wrestling is pretty dangerous...people have died taking bumps.
Pit - Like a fighting pit.
Switch - In a tag team match, you switch in and out of the ring with your partner.
Block - You block punches, kicks etc in wrestling.
I'd go for Pin->Ring->Square, and then one of Swing or Force.
Or maybe Block, that fits better with Wrestling in general...

Not bad.
