It's the fielding positions that I think put many off. You've got leg side and off side, which also means that leg side is on side. Then you've got things like third man, who is completely alone near the boundary and their complete opposite cow corner. You got silly, short and long fielding positions And of course all of these switch sides depending on if the batter is right or left handed. Plus a bowler bowling over or around the wicket, again depending on which arm he bowls with. Not to mention seam, swing, off-spin, leg spin, yorkers, beamers, bouncers, full tosses, googlys, doosras. Is someone a medium-fast or a fast-medium? Have they bowled length or full or short/back of a length?
And that's before you even get near lbw which makes offside look like the rules of guess who.
