to hit one in the testicles by complete suprise,although it doesnt have to be a complete blow,it could be used just to make one flinch. this term was developed by Matthew Skura, Michael Manns, Lewis Cafarella, and Mark Manns of Buffalo, NY. (note: hitting one in the sac wasnt developed by these people,only the term to do so.)
Matt says to Mike, "Watch this Lew is coming down the hall and im gonna give him the biggest sac shot he's ever had!"
