Percentish 

An estimate of a percentage (like "guestimate").

Lou is not sure of how many apples are in her fruit basket - but it looks about half-half... therefore the percentish is 50%~ The mathematical symbol looks like % (percent)but using a tild on its diagonal: o~o, shorthand %~ ("Percent-ish").

Law of the Lesser Percentile

The law that states whichever phone is at a lower percent gets priority on the charger. Given there is only one charger, the lower percent gets access even if someone else is currently using it. They must give it up.

Tony, give me the charger! The Law of the lesser percentile states that you have to give it to me considering I’m at 12% and you’re at 45%!

PerceptIS 

an IT support company, that works exclusively with Case Western Reserve University in Cleveland, OH. This company is probably the worst IT service provider in existence. The continually wrongly diagnose problems with computers, usually assessing that they issues are more severe then they actually are. No matter the desperation you find yourself in, do not resort to taking your computer there to be repaired, as they will usually damage it further, or be of no help, however they are prompt to bill you!

Kid 1: Dude did PerceptIS get your computer fixed?
Kid 2: No, i brought it in because i was missing the "F" key, but they ended up setting it on fire and now its a charred pice of garbage.
