In games requiring teamwork, the "padder's" contribution to the team effort and their team's capabilities usually suffer as a result.
One probable origin of the expression is the video game Battlefield 2, where various, originally supportive activities could be abused to gain individual score without actually contributing to gameplay. In Battlefield: Bad Company 2 the tradition continued, as reviving dying players repeatedly with the defibrillator "pads" yielded relatively high personal score, but in most instances contributed little to the team effort, as the medic would essentially abandon all other activity, sometimes even being counterproductive by preventing teammates from playing freely.
padder> "OH YEAH #1"
player> "we lost you statspadding dick, you cost us 30 tickets for your 2 kills"
padder> "YEAH BUT I AM THE BEST"
player> "no, you're just a score whore"
*player has joined the other team*
Red1> "god I hate stat padding"
Red2> "same, I just got revived three times in grenade spam"
Red1> "I know right, you're just stuck there, dying over and over again because some asshole keeps reviving and not shooting the enemies"
One of the most common occurrences is when 2 support players go out to the middle of nowhere and alternate tossing a grenade, then resupplying the other, each time getting 1 resupply point.
The extreme of stat padding is when a player coordinates with one or more players on the opposite team to get an enormous amount of kills. For example, a USMC player hides away with 2 MEC medics. The US player will kill one of the medics, then the other will revive him, earning the US player 2 points for a kill, and the MEC player 1 point for a revive, all undeserved. This process can be repeated indefinitely, as the kill does not reduce the ticket count of the other team. This is how some players have best round scores of 800+.
Some players consider skill concentration to be stat padding, but this is simply not true. Running around wielding only a pistol in order to get a pistol badge is NOT stat padding.
On a side note, stat padding violates the EA Ranked EULA. Thousands of players have already had their accounts reset due to excessive stat padding.
