What is Ac -10?
1.
To kick ass.
I'm fairly certain that the AC-10 Award, which comes from Goldeneye and Timesplitters, is a reference to Dungeons and Dragons. AC stands for Armor Class. The lower the AC number, the stronger the armor i.e. -10 being very very high. Thus, one who won the AC-10 award in Goldeneye and Timesplitters was one who horded the armor. However, since the games' makers nenver explained what the award means, it seems like it was doled out to whoever kicked the most ass (which one tends to do when one hordes armor). Thus, as both games are very popular, AC-10 has moved into the popular lexicon to mean "ass-kicker."
"I got the AC-10 award the other day on that presentation."
