Sig is someone you'll completely fall in love with. She's funny and really cute. She always thinks positive and see's the best in people. If she falls in love with u ur probably the luckiest man ever. But don't break her heart tho cuz she'll crush your scones.
Someone: I had such a bad day :(

Sig: just stay positive and everything will be fine! <3

Sig is a person that is obsessed with a singular thing, and is good at anything else related to it. They will usually die doing whatever they are obsessed with. The thing they are obsessed with is usually an activity or talent. They are very funny and a fun person to be around. Sig is usually gay or better than everyone else. If they are better than everyone else but then aren’t, they probably realized they are gay. They are mentally not okay and always wear crazy socks. They love video games and cars, and have a knack for things that move. They like loud things, and like listening to music. They also eat a lot of candy and sweets but somehow look fit.
Sig decided to eat three chocolate bars and then ride his skateboard to his death.

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.
Mitra: Did you hear that Scott is still going to the Kidz Bop concert because he bought advance tickets ten years ago?
Josh: sigz classic sunk costz

Piyush: "Yo, did you see that video where the hedgehog eats a birthday cake?"
Josh: "Yupppp, im still siggling"

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."
