SIG 552

The best subcarbine assault rifle ever made. Made by SIGARMS of Switzerland. Fires the same .223 round as the standard US M16. It is 29 inches long with the stock extended, and 20 inches with the stock folded in. The perfect blend of compactness, stopping power, and ergonomics.

My SIG 552 can take on a P90, a G36C, and an MP5, and outshoot all of them.

Sig Fig

a person whose personality fades when they become attached to their significant other's Figure. They begin to like only what their signficant other likes, even if they used to like it before, and even in some cases, including their friends and family. In essence, they change themselves to match their new lover's personality better, much to the dismay of their friends and family. Person has no problems ditching their friends and family for whatever their new lover wants to do.

She becomes a total Sig Fig whenever she gets a new boyfriend and never talks to her friends.

Sig wig

A poorly disguised internet forum username, which reveals your identity immediately, thereby subjecting you to extreme ridicule.

The username could be the name of a company you have worked for and is generally accompanied by tell tale grammatical errors, which immediately point to the author's identity.

"Hey guys..have a look at this! Its our ex mailroom boy Andrew again, posting on this forum using a Sig wig."
