Fi Shi 

Typo for fo'sho'. Occurs during a random group chat. Never retires. Never dies. Just like the sisterhood it stems from.

Sons of Anarchy party this week?
Fi shi!
Oops I meant fo sho
..I like it
Fi Shi!!

Sci-fi survivor 

The collective noun for actors who get bit parts in many different sci-fi tv shows. Dying in Star Trek only to pop up later in Star Gate and then walk onto the set off DS9.

Hey look it's that guy!
Didn't he get killed last week in Babylon 5?
Yeah but he's a Sci-fi survivor .
Hence him appearing as a doctor in Battlestar Galactica.

Wi-Fi spy 

Someone that checks how long you're on the internet and what you do on there.
(e.g. Your Mom)

Person A: Learned something new about my mom today.
Person B: What?
Person A: She looks at everything I do on the internet.
Person B: How do you know?
Person A: I got into a flame war, and she scolded me because of it.
I never showed her my phone, so the only way she could've known is by checking on my search history.
Person B: So she's a Wi-Fi spy.

Ubuntu Wi-Fi Settings 

Where atheist computer nerds go instead of hell.

Man, he didn't use the checksum on the new Tails download? The IISG (Ironic Internet Security God) will make him run Ubuntu Wi-Fi Settings tech support for like... decades.
