1.
In baseball, a pitch that is difficult to hit due to movement rather than velocity or power, such as a breaking ball or a knuckleball. A junkball (or "junk-ball" or "junk ball") will often be caught by the catcher in the dirt. It is often just as difficult for hitter to hit, as it is for a catcher to catch. Bill Lee, Pedro Martinez and Tim Wakefield of the Boston Red Sox are known to be junkball pitchers.
A catcher for a junkball pitcher should have a large glove and a quick eye.

A combo of Football and Basketball played outdoors where teams ranging from 2 to 5 play. To score a team must get a ball usually a Kickball into the hoop which is a car trunk,the cars are parked across from each other in a parking lot usually 3 to 4 spaces apart depending on number of players. The Name JunkBall Comes from the fact that what ever is in the trunks stays making it harder for the ball to stay in the trunk. If a Ball bounces out it does not count. Checking and pushing is allowed.
