Your standard or "basic" crossover is just bouncing the ball with one hand over to the other in front of your body. It can be added to by dribbling the ball from hand to hand more than once. That is called a double or triple cross.
A hesitation crossover uses timing as an advantage; the offensive player hesitates for a split second before doing a crossover to keep the defense guessing. The reasoning is that only the offensive player (ball handler) knows when they will execute the move.
A shammgod is a move that was first done by basketball player God Shammgod and has been copied by many players since. It is an extremely flashy crossover move that only needs one hand to complete. The first part is the same as the standard crossover, and the ball is "crossed over," but before it gets to the other hand, you snatch it back the other way.
A crossover drive in basketball is when a player conducts a crossover dribble move and drives to the basket in the same motion. This is a common move because it surprises the opponent and forces them to follow the ball, which travels from one side to the other.
