Simply, a precept to always "Leave Shit Alone" -- A concept enumerating the fact that things don't break unless they are messed with first. Normally applied to computers. People like to tweak settings, install unneeded tools, etc. But the LSA Rule can be applied to many other things in the world. See murphy's law.
"Damn, my PC keeps locking up! I guess I should have followed the LSA Rule and not installed that adware!"

Get the LSA Rule mug.
A British secondary school located in Lancashire known for being tough and ‘ard. Boomers and Chavs alike accumulate the school grounds and it isn’t uncommon to witness the sight of a student either smoking in the toilets, jumping someone else or writing their name with a compass on the science desks. The teacher’s are a giant meme to the student’s and PWH, MRO, APR, GLE are just meme machines.
A: “that kid appears to have been been smeared in shit”

B: “oh he just attends LSA high school”

A: “Explains a lot”

This phrase is so powerful, that even Google crumbles under it's reign! When you search this word, you get less than 5 results! The definition of this phrase is as follows: "HELP ME I AM BoReD OUT OF MY MIND I nEeD MEDICAL HeLp"

Sidenote: If you delete the "asdf " at the beginning, the phrase loses most of it's power, and only means "im kinda bored lol".
