(n.) a splinter that is so big that it goes all the way through your finger, breaking the skin a second time. It really hurts.
Man #1: "Hey BChil, can you helpus get these wooden steps in place in front of the stage?"
BChil: "Sure. I could really use a good compound splinter right about now..."
A little pest who likes to burst into your room while your doing homework, or playing on your phone. They like to hit you, then like a little bitch, they tell your parents when you hit back. In other words...they are annoying. They are so annoying they make you feel like banging your head against the wall so hard you lose all your brain cells.
You: *on your phone*
Younger sibling: *bursting into your room and runs up to you* Hey!
The art of Splinter Cell-ing involves entering a cubicle and graciously performing a dump, without touching the surrounding toilet floor or the toilet itself. This can be performed as a simple one-person challenge, or be used as a practical joke by remaining off the floor undetected until the next user of said cubicle enters and the surprise is released.
Jake: I just used the toilet, and felt a dripping on my head, I looked up to see Sam Fisher himself about to shit on my head Steve: That's the best performance of The Splinter Cell ever!
Nonsense technobabble used in a production context.
Reticulating splines started off as an in-joke at Maxis and grew to fame with the widespread popularity of The Sims. While it does have a "real" meaning, this definition isn't actually correct in the context of its use. It's really a programming joke.
Reticulating splines is essentially filler. Don't want to describe what's holding up the program? It's reticulating splines. Why isn't the Internet working? The splines aren't reticulated. Heck, don't want to explain your calculus assignment? We're reticulating splines this week.
