A silent internal giggle (SIG) is a rare derivative of LOL. You may be able to catch it if you wake up before daybreak and sprinkle fish feed at the top of the nearest mountain above 4000 feet. Then, and only then, may you be able to summon the power to become one of the few users of the term, if one of the following situations occur:

- when you can't muster the effort to actually LOL
- when you can't muster the effort to pretend even one more time that something is worthy of an LOL
- when you need to disguise the fact that you're watching hedgehog videos during work hours
- when a friend messages you something funny about someone who is in the same room as you

... then you would opt to SIG rather than LOL.

Of note, your dad does not need to go to the mountain top to use this term. He only needs to pretend that he's back in his sorority days for multiple uses of the term to spontaneously occur.

Less than 42 people have ever understood this term.

Karina: "Eeks I just laughed out loud at a pun during an all-staff meeting and realized I wasn't on mute!"
Josh: "Dude, get siggy with it."

a Philapines Sig Sauer is a single shot or full auto only with 3d printed mag loading arm and extractor and a special disconnected trigger leaving the pistol as a fully automatic centerfire .25acp cal or .22wcm with up to a nine inch 150 shot magazine if you line the barrel with aluminium. made of plastic primarily but contains metal to conform to law. none nuclear unless you line the barrel for sustained fire.

$6.99
you can compare the Philapines Sig Sauer m1911 to capones baby machine gun if you add a nuclear barrel. currently slamfire single shot disposable ghost sabot. need a 3d printer to complete it. my beloved project backup weapon. i always wanted to gunsmith.
