Gym term.
When you can only bench 135lbs but you put 200 because a cute girl is nearby, and you do 1 rep/half-
reps.
Can be used for other exercises than
benching, but benching is the primary
target.
Dude, you're overballing with that 200.
That girl won't look at you anyway.
You gotta stop overballing, you'll
break your shoulder.
