Signoff six 

Generally when the last six or seven people are left on a basketball court while they are all just shooting around, waiting for their mommies to pick their broke asses up since they can't drive or afford their own car. It's where most of the bullshit stories of beating other guys in a 1 v 1 and making impossible shots take place. It is also noted that most of the conversation that takes is 99.99% trash talk.

"Hey did you go play basketball yesterday"?
"Yeah, after like 7 only the signoff six remained".
"Is that why Tyrone keeps saying he dunked on you?"
"He's punkass bitch, I swear I beat him 9-0 yesterday"

The Final Signoff 

When you signoff of AOL Instant Messenger and never sign on again. This usually occurs in the early to mid twenties when people decide that the AIM game has nothing more to offer them

It was late one night... I was drunk and going through my buddy list finding no one that amused me... and I signed off for the final time... Its the final signoff.

illegible sign-off 

When you have to sign off on something but the recipient actually needs to hear 'suck a bag of dick' or 'Go fuck yourself'

Dear Cst,

I'm so sorry that when you were so busy getting high on yourself and showing your powerful ability to have a complete lack of regard for human life, you bumped yourself on my elbow while you were throwing me around. In the future, instead of assaulting you with the sheer fact that my body even exists, I will hide in the bushes and try not to breath instead of asking for help.

Sign-off monkey 

A person who has a steady, reasonably-paid job that involves upholding standards who is happy to add their signature to any wrong or unethical thing that their employer asks them to sign off. Some examples might be a careless employees working as an Environmental Officer in a local government authority, a Social Worker in an under-staffed Department of Community Services or a Safety Officer at a mine site.

The last person in this position was just a sign-off monkey so for the first couple of months I was mostly sorting out problems.

Signiffy 

An endearing term for one's significant other when the relationship status is iffy.

They were still in love, but their future together was in constant flux. He was her signiffy, and she his.
