NAC Swap 

Something exclusive to call of duty and gmod, where you press Y at a certain point in an animation and it changes weapon instantly, it can be done with many different things and requires very fast timing to get them consistently. Unless it is a Moni NAC.

"Wow, did you see that tag NAC swap prodan hit on derail in Despize cams 47?"

Nac rat 

Someone who comes from the small East Texas town of Nacogdoches but is trashy. Nac Rats get drunk and start stuff, they never really leave, and they're low class.

Guy 1: Did you see that guy? He's so hillbilly.

Guy 2: Don't mind him, he's a Nac Rat. It's what they do.
