Ladding is when you snap a pic of someone's crotch without them knowing. If you catch someone's crotch facing you, that's a premium lad. If you get someone's butt, that's an anal lad. If you get someone from the side, that's a sidal lad. The best ladders get zoomed in or have a big bulge.
I took a premium lad of my teacher while she was walking down the hallway.
My mate got an anal lad of the barmaid when she turned around.
I snapped a sidal lad of my friend's brother at the gym.
