Bob-ombs have been used as items in several Mario sports titles. In Mario Kart: Double Dash!! they were Wario and Waluigi's special item. Petey Piranha and King Boo also can possess this item because they have the ability to get any special. Like in all Mario games, it is dangerously explosive.
The Bob-omb is an attack Item. It can be thrown ahead of the user's kart to try to knock over the opponent up ahead. If no one is near the Bob-omb, it will take about four seconds to detonate automatically. However, if a racer is near one, or if it thrown and lands directly on a racer, it will blow up right away. The blast radius is about 10 feet, and throws any kart up into the air (similar to a Blue Shell.) However, if a racer drives into the explosion, they will simply spin out.
The Bob-omb can also be dragged and dropped behind the kart. Using it as a shield against other Items such as a Green Shell or Red Shell is a bad idea (really bad idea) because it will blow it up right behind you. One strategy is that when you get a Bob-omb early in the race (when players are usually close together), drop it right behind you so multiple racers will be enveloped in the explosion.
The Bob-omb can be used as a defense against Blue Shells, but it is rare to have a Bob-omb is 1st. If you do, simply drop it behind you right when the Blue Shell is about to come down on you, and it will destroy the Item (extremely helpful technique!) The same goes for Red Shells and Green Shells.
