sig

Short for "signature". Most recently used in relation to forum signature images.

Person 1: Have you been over to Allen's sig shop yet on the forums?
Person 2 (proudly): Not yet... I'm still using the sig from the last forum I was admin of.
Person 1: Dude... It's a pic of a baby in a diaper... This forum is about high-powered weaponry... Get a new sig, man.

They are a fire arms manufacturer that is popular for their line of SiG SAUER pistols (they also manufacture rifles and air soft pieces).
